I really liked the concept of not being able to jump and relying only on the gravity switch, but the real extra difficulty came from the fact that you have to cycle through each wall being the floor rather than directly switching. I definitely think this is a nice idea, but maybe it could be refined a bit to get rid of some of the tediousness that comes from some of the nondeadly switches needing 2 or 3 switches. Overall nice game though!
