I got stuck on the first level, I don't know if the camera is supposed to move to the next room after having gone through the door. Do let me know so I can update and give it a propper rating!
Small simple yet effective. Its most deffinitly a great start! assuming the jumps can be a little tricky with the perspective's and I'd suggest adding automatic camera switches and maybe a UI element showing you which camera your on and how many there are.
