This is a really cool idea, but it's a bit annoying to play since the movement is pretty slippery, which makes it hard to judge when to jump and makes it very easy to fall off when you're trying to land on a small platform. It would also help if it were a bit easier to hit switches since there were a few times were I thought I'd hit one but was just a bit too early or too late. But overall it's really solid for 72 hours of work!
