Do you know what the difference is between this game and Super meat boy and the binding of isaac is? They have a point to get to. This just feels like missle command revamped. No story line, it takes an incredible amount of leveling up to get weaponry... Also you said the game is addicting. It isn't.
Take it from me, next time, try an interesting storyline or a concept other than space invaders with better graphics. Good luck.
