A very cool implementation of the theme.
I was very amazed that the game was actually very good balanced for me. The controls are fairly straight forward so you can directly start playing and the first levels were also quite simple to get into the game. But after the 7th stage it really got hard and this is a positiv thing because I like to figure out mazes.
The only thing I would maybe change are the graphics, because they not fit the game 100%.
Nevertheless a very cool and interesting game so keep it up :D
