The plot, which is even more bare-bones than the first game, revolves around The Lad attempting to find The Kid, who is now The Guy. (Yeah, it's kind of confusing.) The Lad has a slightly more versatile arsenal than The (new) Kid - in addition to the jump and normal gun, he can fire charged shots and use a Grappling-Hook Pistol. In addition, the game runs on a new engine, and in general looks nicer.
Find it here. So far, only the first three levels are available.
This game contains examples of:
- Background Boss: Like Mike Tyson in the previous game, Bald Bull, or Mr. Sandman on the hardest difficulty, fulfills this role.
- Charged Attack: The Lad can charge his gun into a more spectacular and large bullet, much like The (former) Guy's.
- The FAQ page claims Gaiden is a ROM hack of Cheetahmen.
- In the game itself, at the end of the second level you meet the boss over a bridge with an axe on the other side. If you played the first game, you should know what happens if you jump on the axe if you don't, you get a trophy called "No pattern recognition".
- Easy-Mode Mockery: Unlike the original game* , there's an Easy option here. Selecting it closes the game and opens a Barbie flash game in your browser.
- Establishing Series Moment: The original IWBTG sets the tone with spiked walls from unexpected directions and fruits that are not only deadly, but fall up. That's pretty merciful by Gaiden's standards; this game will try to kill you on the world map, before you've even entered the first proper level.
- Everything Trying to Kill You: Even the world map gets in on the action!
- Gaiden Game: Despite the use of the word "Gaiden" in the title, it's not an example.
- Game Over: Press 'Retry' to try again.
- Grappling-Hook Pistol: The Lad can use one.
- Gratuitous Japanese: On the title screen. If you can read Japanese, you'll see it says "WannaGuy". Furthermore, this might not be intentional, but "wana" means "trap" in Japanese.
- High-Pressure Blood: Unsurprisingly.
- Hitbox Dissonance: The grappling hook often grabs nothing but air, but works anyway. Despite how this might sound, it's almost never to your benefit.
- While the previous game had a lot of Shout Outs, Gaiden has a noticeable Bionic Commando vibe to it - the new protagonist is named The Lad (ala Ladd Spencer) and is colored green, and has a grappling hook. The first two levels are based off the game as well.
- In 1-3 Sweet Grave, a revisit to the beginning of IWBTG starts right where The Life-Ending Adventure starts its rendition of IWBTG, complete with some of the same traps, such as a suddenly-double-sided spike platform. Kayin himself, in a Skype call on Gaiden's release, stated that the correlation was purposeful.
- Interface Screw: If your version of the game's out of date, the screen is flipped upside-down, with reminders on the top and bottom of the screen telling you to update. Which are also upside-down.
- In-Universe Game Clock: The traps change their patterns or increase in number when you play at night, and the title screen noticeably darkens as well.
- Kid Hero: Well, he ain't called The Lad for nothing!
- Ludicrous Gibs: The Lad, like The Kid before him, explodes into a shower of red pixels on death, with only his head intact.
- Nintendo Hard: Just like its predecessor. Again, you have unlimited lives and checkpoints, so feel free to die as many times as you need to. Which will probably escalate into the hundreds and then thousands very quickly.
- Nostalgia Level: Stage 1-3 takes place in an early area of the first game, recreated in full with a Background Boss taken from Punch-Out!!... but it's got some new tricks up its sleeve.
- Overworld Not to Scale: Directly based off of Super Mario World... and it has traps as well.
- Platform Hell: It's a sequel to one of the most legendary Platform Hell games ever to exist, so it's to be expected.
- Press Start to Game Over: While the original IWBTG lets you get killed in a matter of seconds, Gaiden takes it to new heights by introducing an overworld map...that tries to kill you...before you even reach the first stage! Good thing this game offers unlimited lives like its predecessor!
- Reference Overdosed:
- The version that Floe played at EVO 2012, which is playable by the public via a code, has a boatload of FGC and Twitch allusions.
- Use of the EVO official logo
- Use of Twitch emotes, such as DansGame (also known as the Floe Face), Kappa Ryu and PogChamp in place of fish in certain places. Includes using the SwiftRage emote for one boss.
- Various soundbytes that play after a death:
- Mike Ross' "I was hustled, man!" (from Excellent Adventures Season 4 Episode 5 with Combofiend)
- Gootecks' trademark laugh
- UltraDavid's "What are you standing up for?" (from Ricky Ortiz vs. Wolfkrone in SSF4 at UFGT8)
- Shao Khan's "You suck"
- Sequential Boss: The fight with Bald Bull/Mr. Sandman runs through several screens, and on each one he has a different attack pattern and requires a different way of damaging him.
- Unskippable Cutscene: Averted entirely: just press Fire 1, Fire 2 and Jump. This can skip Bald Bull/Mr. Sandman's intro as well as the outro after defeating said boss.
