An official 2012 sequel to the original The Great Giana Sisters.A mysterious crystal appears in Giana and Maria's bedroom, creating a portal which sucks up Maria and takes her to the dream world. Giana gives chase.The game is the first game by Black Forest Games, a company consisting mostly of people who also took part in the development of the (quite unsuccessful) Giana Sisters DS. The development of the game was crowd-funded through a Kickstarter campaign under the working title Project Giana.Gameplay-wise it stays true to its 2D platformer roots, but it uses a modern 3D graphic engine. A key gameplay element is Giana's ability to change between her normal cutesy form and her pyrokinetic punk form at will. When she does this, the dream world around her changes in the opposite way. While Cute Giana plays in a creepy nightmare, Punk Giana plays in a Sugar Bowl world. However, the graphics aren't the only difference between the two worlds. A lot of game elements behave different depending on what world Giana is currently in: platforms appear and disappear, gates open or close, elevators change directions and enemies change their behavior patterns.Twisting the dream world also changes the game's music. Cute Giana's dreamworld features music by the original game's composer, Chris Hülsbeck, while Punk Giana's dreamworld features music by Machinae Supremacy.As of September 11, 2013, a standalone expansion named Rise of the Owlverlord has been made available on Steam and became available to play on September 25.
Art Evolution: The game received several updates that enhanced graphics and some controlling goofs. And as a straighter example, the game is considered by many people light years better than its predecessors.
Back for the Dead: If you're not familiar with the game, it makes you think it's invoking this trope with Maria, when the Gurglewocky swallows her whole and all, but it ultimately turns out to be an Averted Trope at the end.
Mechanical platforms that have a red or yellow light on them can be manipulated by world-switching.
Swimmable water is blue (bright and clear for Punk Giana, pale and somewhat murky for Cute Giana), while deadly water is either sickly green (for Cute Giana) or bright, unnatural, grape-punch purple (for Punk Giana).
Checkpoint: Plenty in every level even in Standard Mode. Hardcore has none, however.
Christmas Special: In the form of a stand-alone freebie downloadable Christmas-themed level, complete with snow, Christmas trees, snowmen, and enemies with Santa hats.
Collision Damage: From every enemy around. Giana can also do the same by hurling herself in flames against them.
Cowboy Bebop at His Computer: There are an awful lot of reviewers out there who believe the 'Sisters' portion of the title means that Cute Giana and Punk Giana are sisters rather than being the same person.
Dual-World Gameplay: You switch between a cute and cuddly candyland and a gothic, borderline terrifying overworld. Giana also switches personalities based on these worlds (between Cute and Punky).
Easy-Mode Mockery: Beating a level in Easy will not unlock the next level in any other mode (Standard, Time Attack, Score Attack), also you will not be able to earn stars for ranks and unlock boss levels in Standard.
Evil Overlooker: The final level has Gurglewocky ominously glaring at the screen.
Excuse Plot: Your sister was pulled into a dream world and has been captured by a dragon. Go rescue her!
Face-Heel Turn: Somewhat. Word of God states that Giana became sick and tired of anything that Tastes Like Diabetes (which used to be her fancy), and would now prefer to stomp anything cuddly into the ground. Mind you, she's still good.
Fake Difficulty: Although not often, there are traps and certain segments full of enemies that will kill an unwarned player at least once.
Freaky Is Cool: Giana feels at home in what some would call the nightmarish landscape, thus she appears as her normal bubbly-looking self there. However, it appears the dreamy landscape is so sickeningly sweet that she turns into Punk Giana in a desire to stomp everything into the ground.
Guide Dang It: Minor one: You still can jump if you walk off an edge, that may help in crossing certain places or even save you from death. This, however, was corrected as the hints in the loading screen may inform you, and in The Rise of Owlverlord it tells you straight out.
Harder Than Hard: Hardcore note No checkpoints in the level. and Uber-Hardcore modes note Die once and it's Game Over, you'll have to start all over..
Instant Awesome, Just Add Ninja: One of the Owlverlord's two forms is a ninja form. It's his nastier form too as the throwing stars he chucks at you spread out and are harder to dodge than his cannon shots. Add in a homing projectile and you've got yourself a genuine Bullet Hell on your hands.
Invincible Minor Minion: Armored Demowls. They're basically moving spikes, expect to find a lot of these on descent and uprising segments.
Little Miss Badass: Giana in her punk form, though a case can be argued for Cute Giana as well, who treats the nightmare world like a playground.
Mascot Mook: The Owls grew into this pretty quickly when Project Giana was announced.
Magic Skirt: Maria's skirt stays up while she is dangling upside down in the first level.
Marathon Level: The levels become progessively longer with each stage. Level 1-5 is the first to truly feel like this.
Meaningless Lives: Played with. You may die as many times as you can; however, in Standard Mode, dying too many times prevents you from achieving a good rank, in Hardcore you get thrown to the beginning of the level and Über-Hardcore dying means Game Over.
Mercy Mode: The Easy difficult added after an update. The game is still Nintendo Hard, but on Easy, certain platforms will appear to help the player and even avoid death, there will be less traps, certain enemies will be slower and invincible mooks will appear much less often, and finally, bosses will have extra shields and something else to aid the player.
Multiform Balance: The gameplay is pretty much built around this trope. Switching back and forth between Giana's cute and punk forms at exactly the right moment is the key to solving many puzzles.
Nightmare Fetishist: Almost literally; Giana is much happier while she's immersed in the more nightmarish-looking world.
Ninja Pirate Zombie Robot: The Owlverlord switches between a pirate form with a cannon built into his peg leg and a ninja form who spams throwing stars.
Nintendo Hard: The game becomes progressively harder after the Difficulty Spike. Once it let your hands go you'll be facing long, gruelling levels that requires fast reflexes and keen eyes to achieve the highest ranks.
Perky Goth: Punk Giana. Cute Giana is this as well, as the Kickstarter Web site describes her as liking things spooky (even gaining more powers as the dream she's in gets more morbid.)
Platform Hell: Doesn't seem obvious in the early stages, but the game takes a massive difficulty spike fairly quickly.
Playing with Fire: Punk Giana can curl up and turn into a literal human fireball in her world, allowing her to bust through bricks and scale walls.
Puzzle Boss: Almost no boss can be directly harmed by Giana's attack, instead she must use something to damage them.
Hansel & Gretel: A device which raises a spike as Giana swap between her forms must be used to hit the boss's head(s).
Octor Freud: The only boss that actually can be harmed by Giana, however only one part of him is vulnerable and the floor will change with Giana's form forcing the player to be very careful while dodging his attacks to avoid dying instantly from the Bottomless Pits.
Gurglewocky: In order to gain a way to damage him, you must first let him spit a meteorite that homes at you constantly. When he uses the flaming breath around the room, change to the other form, "disabling" it, and then kick it to his face.
The Owlverlord: In order to hurt him, you must dodge his attacks until he throws a seeking projectile. Then you must survive both the seeking blade and the shots/ninja stars he fires at you until he changes form and then you must trick the homing projectile into him while still dodging all the stuff he throws at you.
Puzzle Platformer: Certain segments will require the usage of Giana's transformation and a bit of thinking to proceed and/or not die.
Slippy-Slidey Ice World: The Christmas levels (though the slippery ice becomes lava when Giana is in her cute form).
Temple of Doom: Level 3-4, which is aptly called Temple of Doomdidoom.
Wakeup Call Boss: The very first boss, Hansel and Gretel, is this. The boss is quite fast and has a particularly nasty attack it uses whenever it is hit and becomes faster and more difficult to dodge as the battle goes on.
Wall Jump: Punk Giana's dash attack when used near a wall. Additionally, she can wall jump normally with help of bookcases or a wall with plants.
