Loved it. the controls are very fluent and sleek which gives the feel of asteroids in my eyes. the progression of difficulty is spot on and can get very cluttered with enemy's at times which is nice as a challenge. although the upgrading system is basic from what iv seen(got past skynet and a little further). it would be nice if the upgrade orbs could been like tokens for upgrading your ship between boss fights as for more variety in how you choose to play. but, if you were going for non stop action then i can see why you have chose the upgrading system you have now. Could really see myself playing this game a lot and it really deserves a spot on Newgrounds.
