It's a very interesting game, with a well-planned idea, the problem is that it needs polishing, the alien colliders are horrible, they kill you even if they don't touch you, there's no game feel when you shoot, or when your heart is about to stop, etc. If that were improved, the game would be much better, apart from that, I think it doesn't have sound.

excellent use of the Limitation

Cool game, the demons were very annoying 

I like the lore!

I hate those demons! I hate this ship because when I just figure out how to kill demons suddenly the heart of the ship stopped :D Anyway, good job! I like you sprites and the idea of limitation. It is defenetly lucking sounds and some feedback/juice when you shot etc. I think it will improve the feel of the game astronomically.
