Addicting, for what it is. The concept/graphics/music are a little too repetitive and simple for my taste, but the actual shooting element does have a charm to it, especially when you get powerups. In my opinion there need to be more enemies and more attack patterns. The levels could also stand to be a little shorter since they're so repetitive as it stands now. I wish I understood how the powerup system worked too - there didn't seem to be a countdown or any explanation as to why my split lasers were disappearing.
