Those without controllers need not apply. The higher difficulties make. the AI extremely vicious and the dodging/spacing moves in this game are already very fiddly.
I prefer using a mouse and keyboard. I have 2 360 controllers but I just don't like using them except for driving and flying in open world games like GTA and Sleeping Dogs. I tried action platformers like Darksiders and Batman with both and greatly preferred the m+k scheme. Unless the PC controls are just plain broken I'll always use them.
