I love the concept of being able to switch states and switch players. I do wish that you utilized this mechanic more, though, as it felt more like just playing a platformer where you can switch states two times. Level design is hard, but this has sooooo much potential. There are some bugs like weird collision when switching states. Another thing that could be very helpful to the player is simply having the camera follow the character they are playing as rather than teleporting around at certain spots making it hard to know when the end of the level was vs an area you just couldn't see yet. Obviously audio could also add some polish, but overall the game is actually great with huge potential. The art style could be utilized even more in my opinion as it's unique and can make it artistic. Well done! :) (If you ever continue development on this game, lmk! I'd love to try out/playtest later iterations of it. :) )
