Loved it
I positively loved it! Its a whole new take on the classic space invaders game that really works out. The controls are very smooth and there aren't any glitches except for the one that gave you 2 grand and made you start the entire game over. The bosses were very good too, a favorite being the floating head of that tripod. The only downside appears to be the upgrades: Waaaaay too expensive. There was a point after the first boss where i couldn't get enough money to upgrade anything at all. The addons should be the most expensive, the armor being less. Everything else had prices skyrocketing further than the alien's ejecting from their downed burning wreck of a flying saucer.
Hope there will be sequel, with mini-bosses and new weapons!
