OK, I finally got it to run! :)
Wacky and very original premise. The main character manages to be simultaneously adorable and very creepy. Very nice music.
Some of the visual design could have been a bit clearer. It was not always obvious which colors represented obstacles. Also, the teeth always appear to face the player when standing still, but in reality, the character is always facing either right or left, which matters because of aiming the fireballs... so I would have preferred if we could always see which direction the character is facing.
