After getting the hang of the controls it was really nice to drift around in the maze. The (IMHO) small viewport (compared to the maze size) added a neat extra challenge (as well as frustration at times :D). At one point I got stuck in the wall and could not get free, but it may have been due to my own inability combined with impatience ... :D
The frantic music added a nice stress to the game, even though it isn't really that stressful.
Great work!
