There are many carts on here that involve corruptions of existing games, but as far as I can tell this is something new: a game designed to corrupt itself from the start! Whether this makes for good gameplay is for you to decide. Spikes increase the rate of corruption, so you should probably avoid them. Go fast, and try to reach the end before the corruption takes over everything. You'll want to reset the cart if that happens. Good luck!
I haven't made this game alone, because it's my second on pico-8 and I'm a bit lazy. The biggest help came from @mhughson's Advanced Micro Platformer, which formed the base of the whole game. Without it, this game wouldn't have really been possible (or at least wouldn't have been as good), so big thanks to @mhughson for releasing it! The music is "Dimensional Gate" from @Gruber's Pico-8 Tunes Vol. 2, which fit the game very well and added one of the best consequences of corruption where the music goes all weird. I also used @qbicfeet's horizontal distortion effect, which triggers (for no good reason) when a randomly-selected byte gets corrupted. Finally, I took inspiration from Jelpi's corrupt mode, but altered its corruption code to be more like the "RANDOMTILT" mode from the Real Time Corruptor (also an inspiration for this game). RANDOMTILT has a chance of simply incrementing or decrementing ("tilting") a byte instead of setting it completely randomly, making for slightly nicer corruptions.
My first ever pico-8 game, which is of course based off the first tutorial in the first zine ("squashy"). Very predictable, I know. Just about the only thing which makes this one different from the hundreds of others is that the ball will occasionally turn orange and start obeying gravity. Oh, and the colour choices aren't quite as ugly, among other quality of life improvements. I also used Mozz's smoke tutorial from the same zine, and Pixel's "THICC TEXT" plugin. I think it turned out well!
