NIce high speed platformer. Was startled when I saw the impending wall of what I just thought was fake cheese coming my way. My only nitpick is the speed at which the screen moves from center to it's position really snappy, but in a way that throws me off, especially as it is based on speed rather then just when you press left or right. Makes it so if I dink into a wall, the screen suddenly centers and then pings back, slightly off putting.
I liked the level design as it was suitably challenging and running on the ceiling is oddly hard. Only other little tweak would be in the final level where you have jumps that if you fall in there is no way to recover is just put spikes in there rather then waiting an extra few seconds for the wall of cheese.
