negative: I agree with what everyone said about coyote time, but I think it goes a little further than that. You aren't able to jump while hanging more than half off an edge, which just feels super disempowering to the player. Are you using a raycast down from the center of the player to detect if they're grounded? I'd recommended using a boxcast instead.
positive: I really like the implementation of post processing here, it really brings the assets to life! also the story is silly and the side effects make it very interesting. nice job!
