The Binding of Isaac is a great game, and this is a great, short demo of the full game. However, one minor gripe which I would like to be fixed is the ruffle support. This is because when you use ruffle (I also use the ruffle Firefox add-on), none of the background assets load, and none of the assets for things like the rocks load. The game is still playable, although more difficult. This may just be a problem with my software, but if not, it would be nice for it to be fixed.
