Absolutely phenomenal. There were definitely some head scratchers in here. I could see this being fleshed out into a full release title for sure. The only note that I have is that level 6, for me, was the most difficult level of the game and maybe would serve the flow of the game better if placed a few levels later. It really makes you think about your limitations and the fact that you need two tiles in order to turn around and plan a route before going into it.
