Cool little puzzle game, it's like Snake meets the Königsberg bridge problem! I liked the lighting giving it a bit more exploratory feel than it would have otherwise, it added a lot to figuring out the level. It took me some time to figure out that you could pass through to the other side. Fun music.
Obviously more levels where the concept is expanded a bit would be cool.

I think there are some really neat ideas underlying this game, but the lack of visibility makes it ridiculously difficult to figure out how it works. I suspect I didn't end up discovering all the tiles and couldn't finish the puzzle - but I really like the idea. Music is awesome, some of my favorite in LD38, shame it stops instead of looping :)
