. As can be inferred from the title, Floating Limbs art style and gameplay, it is designed after Joy Mech Fight.The game features ten playable characters, each with three distinct forms: the Normal class plays with inputs and combos typical to the fighting genre; the JOY Mega class increases their range, power and gives them a powered-up version for their specials but disables combos and finally the CHOY Mega class can Double Jump and chain specials together with easy inputs but has low health.
A commercial and feature-complete version 1.0 was released in November 2022. Also of note is that over time it had multiple collaborations with fellow indie fighting game ROBO OH.
The freeware version can be played online on this link.
In August 2023, a fully-fledged crossover sequel titled ROBO OH Vs. Uchu Mega Fight with tag team gameplay was announced during a live event. It is still developed in PICO-8.
This game features the following tropes:
- A.I. Breaker: The CPU rarely blocks or avoids Maxcyber's Foward+Strong Attack uppercut, so with proper timing you can easily beat Arcade mode with it. This is pretty much required to clear Expert Mode, or else the CPU will show just how much of a Joke Character Maxcyber really is.
- All Just a Dream: According to Hananeko's profile, maybe the entire game is a dream he's having.
- All There in the Manual: While the game itself is light on plot and dialogue, the developer has posted some character details on Twitter.
- Anti-Frustration Features: The developer keeps a version with everything already unlocked for convenience's sake.
- Arrange Mode: Version 0.9.7 introduced Challenge mode, which includes:
- Super Survival involves beating as many random opponents as possible. Some will be either small and hard to hit or big and immune to flinching.
- Short Scoring tasks players with scoring as much as possible against 5 random opponents.
- Time Attack's challenge is beating 10 fixed opponents as fast as possible.
- Save The Earth is a shortcut to the pre-final boss minigame from Arcade mode, and the goal is to score as much as possible with well-placed hits that destroy multiple enemies at once.
- There are also special weekly challenges. The very first on February 2022 was a boss rush against the three versions of Kusemono in multiple sizes.
- Artificial Stupidity:
- Maou's CPU will often try to throw the unthrowable Maxcyber when it gets close for several seconds until it decides to try something else.
- Rarely, Bresshi will not switch to his brutal second phase once his HP is reduced enough, allowing the player to fluke out a win. In his second phase he is very agressive but also doesn't seem to perform throws. As characters cannot die from chip damage, turtling away and blocking at zero HP while countering his attacks with extreme caution is a viable strategy.
- Astral Finale: Version 0.9.6 added context to the final battle against Kusemono, as you fight his army on Earth's surface before pursuing him to the Moon.
- Attack Reflector: Choy Uchuzine has a reflector based on Fox's and Falco's from Super Smash Bros.
- Attract Mode: Leaving the game alone on the title screen will make it cycle between high scores, character profiles and gameplay.
- Background Boss: Maxcyber from Robo Oh is only featured in gameplay as a giant robot who attacks with punches and energy beams from the background.
- Badass Bystander: Bresshi is the punk who cries in despair whenever you clear the bonus level by destroying his car. One of the weekly challenges features him taking revenge as a boss far more powerful than Kusemono.
- Bait-and-Switch Boss:
- The final boss, Kusemono, is displayed on menus in his standard mini stickman form and screams for help when fought but then he reveals either of his huge transformations and mocks the player character for underestimating him.
- The game pretends the secret boss from ROBO OH is Masamioh, but he gets knocked aside by Maxcyber a second later. This is mirrored in Robo Oh by Shippooh whacking Maxcyber out of the way when certain conditions are met.
- Big Bad: Kusemono, the stickman-shaped incarnation of the universe who attacks Earth just to "kill time".
- Bonus Level:
- Arcade mode features the car vandalism challenge from the Street Fighter games, complete with the owner walking by and screaming "Oh my God" if you win. By inputting the Konami Code on the main menu, you can freely play this level.
- Version 0.9.6 added a second bonus round where you face meteorites and aliens that are targetting Earth. There are bonuses for destroying multiple enemies at once and even a boss fight against Kusemono's UFO.
- Break Meter: Fighters have an invisible dizzy counter that starts at 100 and become vulnerable once it is fully depleted by damage. The visual indicator for this is them flashing. From version 1.2 on, Joy characters can deplete the opponent's dizzy meter even if their attacks are blocked.
- Cap: The highest score possible within PICO-8 limits is 3276799 and it was achievable in Challenge S11: Vs. Gacha-Man due to it being endless and randomly awarding large score bonuses.
- Charge-Input Special: Joy Blue Moon has analogues of Guile's Sonic Boom and Flash Kick that are performed by holding back or down before inputting the opposite direction and befit a defensive playstyle to counter opponents as they move in.
- Charged Attack:
- Choy Maou's back special is him winding up a punch. At maximum power it blows the opponent across the screen.
- Choy Fujigaya Rei can perform the Focus Attack from Street Fighter IV.
- Classic Cheat Code:
- Inputting the Konami Code (up, up, down, down, left, right, left, right, cancel, confirm) on the main menu displays a free play mode for the car bonus level.
- Inputting left, right, left, right, left, right, confirm on Autofive's mode select for either Arcade mode or Vs. mode will enable Maxcyber.
- Co-Op Multiplayer: As of 1.2, there are modes where two players can fight a single CPU or human opponent.
- Combining Mecha: Autofive is made up of a helicopter, two planes and two cars.
- Combos: Normal characters can chain attacks, Joy characters can't but deal more damage on each hit and Choy characters have a short auto combo on one button. Some Choys have specials that can be used in combos, and others don't.
- Although Joy characters aren't supposed to perform combos due to a lack of Lag Cancel or attacks pushing them away from the opponent, some things still slip past the cracks. Joy Autofive, for example, can use his heavy plane tackle from a distance (which causes it to not knock the opponent down) and just barely chain it into his light car shot.
- After an update enhanced the special moves of Joy Mega characters, Joy Kusemono became able to throw a homing projectile that can lead into a 5-hit combo.
- Continuing is Painful:
- Continuing in Arcade mode costs points, but also spins a roulette on the form your opponent will use so that you might have an easier time (or not).
- Getting knocked out in most of the challenge modes depletes 10000 points and then resumes the fight with the player at full health. "Car Guy's Revenge" is one exception where losing will cause a game over.
- Counter-Attack:
- Choy Autofive's Down Special is him using his sword to parry and counter attacks. It requires very precise timing but can potentially deal a lot of damage.
- Maxcyber's core will flash yellow and then red as he takes damage. If it goes past that he'll be staggered, but the player can convert the core's energy into a powerful triple laser beam.
- Version 1.2 allows Normal characters to guard cancel by spending one Mega Orb.
- Dash Attack: Autofive can disassemble and tackle the opponent, which is a very fearsome move in most of its versions due to its large range and Immune to Flinching effect. If it hits from far enough it doesn't blow the opponent away and can be used as a combo starter. The Choy version of the move is smaller, but it can be performed three times in a row even in midair and in multiple directions.
- Desperation Attack: Joy characters can perform a strong variant of their special moves by pressing both attack buttons at once. At low health, one more special is enabled in their moveset.
- Difficulty by Acceleration: The weekly UMF Dash Turbo challenge increases the game's speed upon reaching certain thresholds in the enemy gauntlet.
- Dual Boss:
- The weekly challenge "Dramatic Battle" requires players to fight two opponents at a time until the wave of enemies ends, in reference to the game mode of the same name in Street Fighter Alpha.
- In Car Guy's Revenge, the last two Henchman will spawn at the same time and the boss, Bresshi, will replace the one who falls first. All of them have very erratic movements, making it difficult to get rid of the last minion to focus on Bresshi and his dangerous Megaton Punch.
- Version 1.2 expands Dramatic Battle into an alternate Challenge Mode with courses where you either fight with a teammate against one opponent or alone against a duo. The boss in this mode is the Megadragon.
- Easy-Mode Mockery: Playing on Easy mode awards endings where the characters don't get a wish granted by God Hasshi.
- Excuse Plot: A single line on the character select screen, pre battle dialogue with Kusemono and an ending scene are all the plot the game has for each character.
- Floating Limbs: As in Joy Mech Fight, it is used as a method for animating many characters within the hardware's constraints. What Uchu does differently is make each character have two more forms by changing the gap between their limbs. Characters in the Joy class are tall and the Choy ones are short (Joy Kusemono is him in a humanoid orb form and Choy Kusemono is just his untransformed stickman form).
- The Grappler: Maou has a command grab that deals heavy damage regardless of which form he is in. In Choy mode he can also perform it while jumping and as a lunge to catch opponents from afar.
- Guest Fighter:
- Version 0.9.5 added Autofive from ROBO OH to the roster while Uchuzine was added to that game in return.
- Version 0.9.8 added Maxcyber from Robo Oh in his natural size as an Optional Boss, with a cheat code to make him playable. Meanwhile, Robo Oh got Shippo in return. He's featured as an Optional Boss in both normal and giant mech forms, but only the normal version is playable.
- Hard Mode Perks:
- Clearing Arcade mode in Hard mode is worth two stars for each character, so unlocking the secret ones is faster that way. Expert mode is worth even more points for the leaderboard, but it has separated tables for each difficulty anyway.
- Clearing Arcade mode on Expert difficulty nets an unique scene for your character after the credits, such as Blue Moon taking her helmet off.
- Head Swap:
- Bresshi and his henchmen are headswaps of Hasshi.
- The Gacha Man is depicted as any of the fighters but with a prize capsule as a head.
- Humongous Mecha:
- The Real Size Robo Oh challenge first required players to play as a giant Autofive with the mechanics from his home game, Robo Oh, against tiny-sized opponents. The final challenger was a giant Uchuzine, who appears in his Robo Oh mech design. The second week of the challenge added Shippooh, the mixed version of Shippo featured in Robo Oh, and let players also play as both him and Uchuzine in this mode. The CPU opponents were changed to just this trio.
- Maxcyber from Robo Oh appears as a secret boss in an unique giant form, fighting the other characters as a Background Boss. Robo Oh also added an equivalent fight against Shippooh as part of the crossover event.
- Immune to Flinching: Certain characters have moves that push against a single hit. Giant enemies in certain challenge modes, on the other hand, cannot be interrupted until they're dizzied.
- Jerkass Genie: On Maxcyber's ending, upon being offered a wish by God Hasshi, he declares that he absorbed Kusemono's power and doesn't need it. God Hasshi exploits the villain's choice of words by depowering him instead.
- Joke Character:
- Utsuuji Man in JOY Mega mode is regarded as practically unplayable. Normal Utsuuji is more grindy but the JOY class outright lacks combos and he becomes too vulnerable in that form without enough power to make up for it.
- Kusemono in CHOY Mega mode has a few worthless moves and dies in a couple of hits. However, his short-range fireball rarely turns into a large one that insta-kills. Jumping around while tossing fireballs and hoping for the best is thought to be more practical than playing as Joy Utsuuji.
- Lag Cancel: Version 0.9.6 allowed Normal characters to cancel a special move into another special move once per combo. Version 1.2 changes it to cost a "Mega Orb" resource, so then it can only be used up to three times per round.
- Limit Break: The Real Size Robo Oh challenge had a playable Autofive and a CPU-exclusive Uchuzine with the super gauge mechanics from Robo Oh. By spending two slots, Autofive could perform his sword slash (which is normally exclusive to his Joy mode at low health) and Uchuzine could perform a spinning lunge.
- Luck-Based Mission:
- To clear Save The Earth with over 200K points (which is only doable with a few characters), you must destroy groups of enemies in a single move while making sure the UFOs are the last ones getting hit and beat Kusemono as fast as possible when he shows up. However, while all the enemies come in a fixed order, the UFOs behave erratically and Kusemono has a random attack pattern. This makes it very difficult to score that high in this minigame.
- The Mushroom Panic challenge has mushrooms and bamboo shoots spawning at random and sliding around to resize either fighter on the field.
- The Gacha Man challenge awards an item for every enemy defeated, but it changes to a random one every time the enemy is knocked down. This includes Coins that are useless, Hearts for HP recovery and delicious Crowns that combine the effects of every other stat booster. After the first opponent, characters and their size also seem to come at random. If you're unlucky, you could get a mini Choy Utsuuji Man zipping all over the place, or a Choy Kusemono that manages to land his random instakilling fireball to bring your run to a screeching halt.
- Macro Zone: The mini characters who can be fought in certain modes have low defense but can be hard to hit. In Mushroom Panic, collecting the bamboo shoot item to get shrunk also heals a little HP, unlike the enlarging super mushroom which only cures the stun status.
- Mad Scientist: Shippo is a former one who absorbed Uchuzine's intelligence for some reason and turned into an otaku. Because of his research, he can travel back nd forth between the universes of this game and Robo Oh.
- Me's a Crowd: The various stickmen mooks in the Save The Earth minigame are also part of Kusemono, who is a Cosmic Entity. Each one is worth a planet.
- Mechanically Unusual Fighter: Maxcyber is a boss character that's also playable but is hidden by a cheat code. As a Background Boss who attacks only with his fists, he has light and strong inputs instead of punches and kicks. He won't take chip damage while blocking and cannot be thrown, but is also terribly vulnerable while attacking. While he seems Immune to Flinching, he can be staggered by constant damage. Out of all characters, only he can convert this stun buildup into a special move. Finally, playing as him forces the game into single round matches.
- Nonstandard Character Design: Unlike the other characters with floating limbs, Hasshi and Choy Kusemono are stickmen. Hasshi also happens to be the one character whose eyes are visible and open. All the others have either Eyes Always Shut or wear a mask, while Kusemono in all forms has a blank face instead.
- One-Hit Kill:
- Choy Kusemono can randomly shoot fireballs that are an instant knockout on hit. On block, it turns into a HP to One attack.
- Joy Autofive's super version of his sword slash at low health deals over 50 damage and dizzies. As super moves can be used over and over, the player can simply cut the opponent down again and win in two hits that might as well be just one.
- Play Every Day: The updates from February 2022 onwards involved challenges that changed every week.
- Power Copying: Hananeko can absorb a single specific move from each character in the roster by catching them with the snot from his runny nose.
- Power-Up:
- The Mushroom Panic weekly challenge involves Mario-like mushrooms that enlarge or shrink the character who catches them, providing a number of advantages and disavantages depending on circumstances. At the time this mode was enabled, it was the only way to play as resized characters.
- The Variety mode exclusive to multiplayer lets both players pick from a set of 10 cards that contain powerups for the next round. Examples include enabling a Big Head Mode, getting ridiculously high speed, turning invisible, giant-sized or being forced to play as Choy Kusemono, and bombs that damage both players repeatedly falling out of the sky.
- Score Multiplier: In the weekly challenge version of Destroy The Car, each character had a positive or negative score multiplier in an effort to balance them. Hasshi had the biggest multiplier seemingly because he was a bad match for the minigame, but his Joy moveset turned out to have the biggest possible high score among the cast.
- Scoring Points: The game has an online leaderboard for each difficulty mode that's shared by all characters.
- Scratch Damage: Most special attacks deal minor damage to blocking opponents, but a few like Choy Kusemono's insta-killing fireball or any of Bresshi's special attacks will deal major damage instead. Characters cannot be defeated by chip damage.
- Shotoclone:
- Uchuzine's special moves are a fireball and a spinning kick that goes either fowards or upwards.
- Fujigaya Rei has a moveset based on Akuma from Street Fighter II. A full set of a fireball that can be shot downwards from the air, a rising punch and a spinning kick.
- The Smurfette Principle: Blue Moon used to be the only female fighter in the game. An special challenge later added Marumoyo-chan, a fan-made five years-old girl.
- SNK Boss: The Car Guy's Revenge challenge features Bresshi, a head swap of Hasshi that is seen crying whenever you demolish his car in the bonus level. First you have to fight 4 agressive mook versions of Hasshi before getting to him, the last couple being faced at the same time. On top of Hasshi's odd, fast and long-ranged normal attacks, Bresshi has two unique specials: a volley of grenades and a highly powerful and armored Megaton Punch (with a lingering hitbox to boot). Once you lower Bresshi's HP enough, he Turns Red with his difficulty set to 10. In this state, he cannot be stunned or knocked down at all and will spam his special moves over and over on top of performing enhanced Joy Mega versions of them despite being a Normal character. Any mistake will get you insta-killed and this is the first weekly challenge with no instant respawn mechanic.
- Stick-Figure Comic: Earthlings in the game are portrayed as stickmen with stretching limbs. In fact, "An earthling. (Really?)" is all the official character profile chart has to say of Hasshi and the other stick characters who resemble him, except for Kusemono who's an alien.
- Surplus Damage Bonus: You can sneak a few more inputs in after winning a round to extend your combo and gain more score, which is particularly important in Super Survival move as points are converted to health recovery.
- This Is a Drill: Shippo Tsuki's Normal mech has drill arms and the Choy version can shoot drill missiles.
- True Final Boss:
- Fujigaya Rei, whose moveset is based on Akuma from Street Fighter II, can appear as a bonus opponent after Kusemono.
- It is possible to get Maxcyber from ROBO OH as the bonus boss instead of Rei.
- An update added a Shin Akuma-like version of Rei and a version of Marumoyo with Rugal's moveset.
- Unblockable Attack:
- Choy Kusemono's insta-killing fireball can be blocked, but it will still deal extreme damage and push the enemy far away.
- Choy Rei has the Focus Attack from Street Fighter IV that breaks the opponent's defense if fully charged.
- Joy Autofive's sword attack with both attack buttons pressed cannot be blocked. It also deals over half a life bar's worth of damage, stuns and doesn't take too long to execute, making it a guaranteed kill on hit and one of the most powerful moves in the entire game.
- Maxcyber has a move where he pulls back and rushes foward to throw an uppercut. Part of his movement is invincible and the punch is unblockable.
- Video Game Tutorial:
- Every character has an in-game playable manual that details their moveset.
- The Combo Dojo mode lets players try out the moves of each character in lessons of increasing difficulty. Trying to use a Joy or Choy character just kicks them back to the title screen.
- A Winner Is You:
- Clearing Expert mode nets a special line of dialogue from each character instead of a request to play the next difficulty level.
- The February 2022 Happy Blue Moon challenge involved her gifting the player with either a bean, cheese or sushi instead of trophies depending on the score after clearing the fight. This is unlike how the previous Kusemono challenge and the normal ones have no unique scenes.
