Very nice and cleanly put together game - lots of polish for what little time we had. Personally I would have placed level 5 at the end, as it gave me the most trouble, but I suspect every player has their own strengths and weaknesses. I would have loved to have opponent erasers, or ghosts of faster times to play against (silentwolf might have an addon that you could leverage to store fastest times/paths to the cloud for people to play against).
Overall, very nicely done.
