Fun as hell!
It's nice to see when someone takes an old concept and gives it a well deserved overhaul. What you've done is taken the space invaders that we all grew up with and really tuned it up, making it a game worthy of today's challenge seeking gamer. The graphics were crisp, the sound was fairly good and the gameplay was simple but challenging, and in a way that makes the game fun and not frustrating. Great job and best of luck in future submissions.
