Looks interesting, but I can't pass the camera control tutorial level. As I move the mouse to control the camera, eventually, the mouse moves outside the browser window, and the camera direction gradually aligns with Sonic's POV before I can move the cursor around the window to re-enter the opposite side to continue moving. Continuous mouse movement seems necessary to keep the camera aligned differently from Sonic's movement direction.

I don't think this is how it's supposed to work.
