Get rid of that auto-pause. And WTFH is with stage 10!? A boss which kills units in one shot!? And worse, at low health he starts firing TWO missiles at once and summons a whole swarm of suicide bombers too!! How the hell are you supposed to ace this thing!? I can't use any expensive units at all!
stage 19 on hard is impossible without a perfect computer, one instant of lag will kill. Hard is more about control than anything and with the speed up it makes it near impossible
How the hell is a person supposed to complete hard with 3 stars? I am using 3 maxed out meteor gatlings and i can't kill them quickly enough. Then there is trying to survive through the bullets. At higher levels it's pretty much impossible to shoot some enemies through the front since the hitbox is the entire plane
