ROM Check Fail (developed by Farbs)
Get it here!
Think WarioWare with a ROM corrupter and add a heavy dose of nostalgia. The main idea behind this game is to clear all the enemies on screen in twenty levels.
Sounds simple? It might have been, except that the game will often, without warning, "corrupt" itself and change the game mechanics, enemies, background, and physics based on old Nintendo games, and will often mix player characters, enemies and levels from separate games. Say, for example, you start off on one level playing as the ship from Asteroids facing off against Goombas in a Spy Hunter theme. You play that for a few seconds, but after ten seconds you're all of a sudden Mario fighting the aliens from Space Invaders in a Pac-Man maze, and after THAT you're playing as Link slashing Arkanoid blocks in the Mushroom Kingdom.
The level design itself never changes, but the physics, controls and enemy patterns do (to match their appropriate games). This is definitely worth a shot, if only for the absurdity of it all, and for those who "get it", it can be HIGHLY addicting, with yours truly standing as testimony to that.
