The audio and particle effects give this game a lot of juice! The tutorial is greatly appreciated (something we only occasionally get into our games) - though I wish the text stayed on screen a little better. There are a couple pages I definitely don't know what they said. I like that you had multiple behaviors of enemies (asteroids going straight vs aliens chasing the player). The difficulty ramped up way too fast for my reaction speed -- those things come in crazy fast. Solid entry, overall!
