The game Idea is really unique and one of the best this Jam, I had a lot of fun playing it.
Having slightly better UX and UI alongside SFX will help.
Usage of shadows is really great. and level design is awesome.
Also you sort of don't have a decent User feedback on when you die or lose so setting a level fail will help and also having a tutorial in game or just explaining what button and what object does what will definitely help.
One of my fav games this jam
