This game is still a little rough around the edges. I agree with the comments below and I don’t have much more to add. One thing that would help immensely is adding a tutorial. That applies to this game or any other you make in the future. Adding in-game tutorials is usually difficult so I’d recommend at least you use the game page text description to add instructions there. For most jams you can even modify the game page after the jam deadline giving you plenty of time to add instructions around things people may get stuck around.
