The aesthetics of this game are great; it's probably one of the best looking games I've played this jam. A lot of work clearly went into making the game look good and unique, the customisation is a nice touch and the sound is decent though it can get grating after a while.
That said, the gameplay needs a lot of work, especially the procedural generation. It's way too easy to end up in a situation where there's just nothing you can do, either because platforms spawn too far apart from each other, because there are too many enemies blocking your only route(s) or both. I like the chaotic feel of the game, but it feels like getting a good score is more luck than anything else. Sometimes I'd have a clear path up and other times I ended up with all the platforms too far away from each other to jump and enemies/obstacles taking up almost every pixel of its space. Bullets you fire should go through platforms because it just makes it frustrating to shoot enemies, especially when they're blocking your path up. You could also do a better job at explaining the game's mechanics. Instructions appear extremely slowly as the camera scrolls up and aren't specific enough. For quite a while I had no idea I could double jump lol. Finally, the player character is just way too floaty when jumping and it's too easy to get killed by enemies off the screen. Half the time I didn't even know what killed me.
That said, this is a great entry with some of the best aesthetics of the jam. Nice work! :)
