Cool but very difficult game. I agree that a timer would be good as an incentive to go faster rather than being extremely cautious. I like the camera effect when you start a new level, and the game is very polished. Also, I think the player should become invincible after finishing a level because I often died after reaching the blue square because I was still holding LMB.

Nice idea. Perhaps a little timer/score based on how quickly people get to the goal could be a nice addition so people feel a need to be as fast and accurate as possible rather than just cautiously moving through the maze.
