what stage makes you want to throw your controller through the screen?
mine are
Heatman, telly spam, and too many jumps that are directly above you and to make things worse, theres one over a pit
Ringman, those annoying guns at the begining, the dissapearing floors, the saturnbots, and not to mention the giant hippo, OH THE HIPPO
Turboman, the stage is made of instant death, jump wrong, a tire bounces you into spikes, time your moves wrong, you lose ALOT of health from fire, and the quickman like flame jet area that kills you instantly, not to mention shademan's weapon is his weakness, but you need his weapon to get to shademan in the first place (unless you trust random springs)
