Seems a nice game. I didn't bother finishing it due to the controls:
wasd on an azerty-keyboard is a pain. (hence I'm giving neutral stars)
If possible an update to the game (or at least to your future games) to either allow arrow-control or even allow people to customise controls. (put the controls in an array, with a button to reset array to default one; then one keypress-event handler in which you check if the pressed key is one of the keys in the array)
