This is what I meant - that I press enter and nothing happens.
That's weird because it works when I tested it out and other people were able to play the game. It could be just be loading issue with itch.io, try refreshing the window and see if that works, that usually works when I played web games on itchio. I think see what you are talking about it loads up the level but then your are able to play the game or move. I think refreshing your browser should do the trick . If that doesn't work click the game screen when it goes to fullscreen mode, sometimes itchio doesn't register web games when the enter full screen mode. Your are more then welcome to try play the game again.
