Fun and creative, but slippery controls
The controls really ticked me off in many places, but especially during the jumping on rats part. Maybe if falling wasn't an automatic death. The first problem is the amount your character moves after landing, the other problem is that you look like you're about to land on the platform and you'll still fall through.
Another problem: I got a tiny bit stuck so I clicked on the "menu" button, not knowing that it would take me back to the main menu and i'd have to start the whole game over. You should have made that more clear.
