but otherwise very smart, simple but fun. the only suggestion is as it goes on you should add a 360 rotating cannon/shield so that your attacked from all sides
really fun i thought it was boring and went to comment but read alex robbins post about the store and i didnt see a store before so thats what brought me back to the game.
honestly very fun for how simple it is. i could see myself spending hours at a time on this game and might even pay for it on steam. the only thing i dont like is.. oh there isnt anything. you should add power upps though.
