I like how you re-vamped the original space invaders. But it's kind of bland. It's already been mentioned about how easy it is, and it is. I got bored at about 30k points and killed myself. There's not much challenge once you get the multi-shot. The graphics were nice and the music is good. But it's just too easy to play. You should try pausing at levels and making upgrades. Everyone likes those. Also try making the AI's a little more difficult. Like they could dodge shots or something. Random change of placement. That way I can't just sit in one spot and let them run into my shots. Good work though.
