The story was really cute! Fun game. Four made me sad. Two made me angry. :p

Hit one bug dying as 2, where the screen just went black and stayed black (though sound effects were playing).

Also, please, please, please add space-bar as another jump key. Died a number of times due to muscle memory taking over... (I'm looking at you, "2").

This game was super cute and you executed it great! I found myself hooked. The different controls for each number made each level fresh and the music really creates a sense of urgency. Excellent work!
