This was fun. The warning indicators are a really nice touch. I would recommend adding a sound que to go along side them, to make sure they are understood better. My one question, is that the player seems to have a weapon but its not used at all. If the game was intended to have a shooter like mechanic then I think you could work to make that fully realized but if not, I say alter the spite so that it doesn't give the player the impression that you can attack.
