I like the concept, the art looks good! I wish it didn't reverse your controls constantly. Pressing a button should always move you the same direction whether you're on the ceiling or ground, and same for the walls. Flipping it I know is more realistic, but in terms of gameplay it just makes it confusing, especially when the game is full of small tunnels where you *really* need to quickly move the right direction after switching
Other than that I enjoyed it though :)
