You are not protected any where!
Even on corner edge battles. The shockwave of firing is so annoying and wY TO MANY HITS FOR EACH DOT! Make them come slowly higher rather than all at once. Like what the hell.
the lvl increasements get 2 fuckin high after a few lvls* everything else was ok
Decent, but flawed.
You need to fix the problem of the spawning enemies killing you. That makes the game way too difficult and frustrating. Solid otherwise.
Tight job man. Really liked the simplicity, and the fact that you could upgrade. It was nice that the balls didn't target you but they could've had a spawn point. I kept losing lives around the edges of the screen... Also the fact that the tank looks different after you upgrade is awesome. Nice Job!
I think it was fun but the enemys spawn so close I lost most of my lives just trying to get experience :)
