Update: the ads have gotten more aggressive. You must click "next" every 10 seconds or the ad doesn't finish... uninstalled game The game plays itself. Blocks drop down and you shoot them. Your guns aim and fire automatically. You need do nothing. Actually your only job is to increase the "power and fire rate" of your cannons. This is done by watching Ads. So the game plays itself amd you watch ads to help. There's no strategy or game play... just watch the ads.
