Graphics and sound are very simple (while the sounds are very fun!), and at least I haven't gotten to the point where it gets really messy because it's pretty hard. I also think that there are no checkpoints, which is quite frustrating. Which is a little unfortunate, because the many mechanics could make for some interesting level design. I got through the first level and then died pretty quickly, but even though the controls felt a bit clunky, it was still interesting.
