I dig the graphics and the rewind feature. Other than that I would have liked some sound and some kind of indication or visual hint to make the gameplay more appealing. But good job :)

The game looks nice, but its not a good combination. A maze without any mark to see if I already beem there or a map, lacks some playability. The rewind feature, when you lose its a great feature in general, and help (a little) the lack of some map or reference.

A maze with a timer might not be a particularly good combo. The game looks nice however. I would suggest to make the player take the shortest path back to the start at game over rather than simply move it backwards.
