As others have pointed out the WebGL build is not working. Also kind of strange to leave the money donation setting turned on for a jam game (when going to download it has the standard itch.io money prompt to donate or “pick your price”).
I think the general concept of the game could have been explained better in the main menu. But the idea is novel and fun to play. My only other gripe would be how slow the player moves. I think if this concept was fleshed out further it could make for a very compelling arcade game.
Also the sound design is great so fantastic job on that front!
