Short and slow-paced.
The game was far too short to be enjoyed. There was little incentive for winning to begin with, but I might have liked another five or ten minutes of play.
I also noticed that there is an issue with hit detection. You can sit about a half centimeter away from the largest squares and still lose points for getting hit.
This isn't terrible, because it was obviously meant to be a casual game and succeeds in this to a degree. It definitely could have used some more work, though.
