A DSiWare game by WayForward, later released as a Playstation Mini title. Could be a described as a platformer/puzzler hybrid as your goal is to reach the level's exit (a froggish Fishman) in each level which you must accomplish through flipping (hence the title) from the top and bottom screens to get past various obstacles.
This game provides examples of:
- Collapsing Lair: The last level will start blowing up once you finish it.
- Excuse Plot: No explanation for why Alta and her gang are flipping through dimensions but one really isn't needed anyway.
- Fish People: The fishman marks the goal of each level. Reuniting him and Alta is the main challenge in each mission.
- Gainaxing: Alta does this with her butt when climbing ladders. Due to the style of the sprites, it is quite goofy.
- I Am Not Weasel: The Fishman is easily mistaken for a frog and even makes a rather froglike ribbit.
- Invisible Block: One of the screens in the final level has you navigating on these. The trick is that the preview screen is also acting as the path for the current screen. Stay within the blocks that are showing in the next screen.
- Layered World: The game's main mechanic is flipping between them.
- Locked Door: In many levels, the player needs to find a calf, a piglet and a kitten for the fishman to teleport you out.
- Mix-and-Match Critters: The calves Alta have to collect are literally called pig-or-cows for a reason.
- Nintendo Hard: Many of the later stages are extremely difficult. Almost enough to warrant tossing your DSi/3DS/Vita/PS3 controller out the window.
- No Antagonist: There are no real enemies out to get you. Spikes, flipping into objects, and the like will kill you many times though.
- Ridiculously Cute Critter: The jetpack cat, cow calf and piglet essentially act as the game's "keys."
- Smooch of Victory: Alta gives one to the Fishman at the end of each level as well as in the ending.
- Spikes of Doom: Needless to say, avoid these.
- Tele-Frag: You die if you flip into a wall.
