Its a promising start! The player and sprite hit boxes interact weirdly, it might be worth changing the spike hit box to be smaller (as indicated below) because it leads to more intuitive hit boxes which line up with what players expect the hit boxes to behave like. Most of the hit box designs like this still cause the player to die if the every hit the spike sprite but gives the players a bit more margin.
I've added some examples of games doing this below as well as a video which talks about some of the other things that you can do in platformers which makes it more enjoyable for people to play.
Obviously, you don't have to take all of this into account if you don't want to, just thought it might be more useful than another "fix hitboxes" comment.
The generation is awesome, I'm glad you got the optimisation working (I'm the Y13 who absolutely failed in trying to help with optimising it). Are you still using wave function collapse or did you have to use something different? The player movement feels a little heavy but that's just my opinion. Cool concept though
Great game, its really fun to play. The only thing I would add is some kind of timer, it feels like, when the later levels are added, it would be really fun to speedrun.
I like the general concept of the game however the lack of a distinguishing factor between player 1 and player 2's sprites isn't ideal. It was very easy to lose track of which character is yours, especially if dash is used.
