Surprisingly addictive even though I struggled to get the hang of it. Since you had some time to spare it would've been good to get the camera to smoothly transition instead of just snapping to new positions which is disorientating. It would be nice to have checkpoints (maybe there were some and I just didn't make it far enough to find them). Also, since you (or I at least) have to restart a lot, it would be good to assign a key instead of a mouse click to restarting.
