They/he/whatever really messed the upgrades up. Auto-turret hardly shoots, and when it does, it doesn't hardly hit. Fire rate and damage upgrades do nothing. Max health upgrade adds 20 health but doesn't fill it, then the restore health only gives 15.
This game fails: extra balls make you lose life. "Bricks" should disappear, not fall and knock the orb down and make you fail endurance mode. Paddle should not be round since you can hit the orb sideways with no lift so you can't catch it.
OMG I got hit on the green cannon and I was trying to get impossible achievement so I just clicked to end it then, and the ball that was out stayed there through the menu. When I started another game, it was still there, not doing anything, and it made me lose a life when I touched it.
