A nice twist on the classic Mario tale, with donuts that go nuts instead of the other plumber brothers. Level design, difficulty and variation is great, though I'd really really appreciate a quality toggle! Unfortunately, you can't even use the right-click menu to toggle quality on this game, and with (I assume) large canvas sizes and dynamic effects, high quality leaves me with a ton of lag on this particular game. Just a small detail, but it affects the gameplay experience quite a bit. Otherwise: great work!
