At the first play of your game (by using only the keyboard) I was confused and thought this game is impossible to beat. Then I read the comment by Andrew and went back to the game and suddenly the game became great :D Maybe you should mention that the player need both keyboard and the mouse to play this game. I've also tried to play the game with only the mouse but it was kind of hard and not so enjoyable as with the keyboard and the mouse.
However, this game ist very nice in gameplay and presentation (especially the crowd feels good and is encouraging). Nice job!!
