Even after many tries, the second stage takes too much of a spike in difficulty; I couldn't get past it. The visibility could be improved; even at the maximum brightness for my pc, it was hard to see where I was or if there was a wall. Still, the art, the aesthetics and the music are really sweet and charming. The concept of the rat king is very cool and promising. There are various things to improve, but what's already there it's pretty good. Keep up! :)
