I like what you're going for here and the short animated sequences at the end of levels is a nice touch that you don't see often in game jams, did you use Godot's AnimationPlayer node for those?
In terms of gameplay there's not a lot I can say outside of there's not much. I would have liked to see some form of more traditional game-loop to play around with.
Visually I think there's a lot to like. The art is solid and the levels themselves are all distinctly vibey, though I did find the sprites not billboarding pretty distracting and it took me out of it every time it happened. I could see a retro viewport shader of some kind really benefitting this game to help pull together the partly clashing level and character designs.
In terms of audio I would have loved to have some kind of ambiance or background music as well as footstep sound effects.
Congrats on shipping a game!
