Very COOL!!! The COOLEST game I've played so far. Games like these are the sort that truly heal your soul. If you continue making games like this, you will be doing the world a favor - I mean that. I think some of the most important things you could add to this game would be a sound effect for when the player ship gets damaged, and a level select menu. Regrettably, I died in space - but I enjoyed every second that I played your game. Great work!
