Yeah I had no real problem with difficulty overall but I feel bad for some out there. One thing I hated was the invisible enemy that would pop up and devastate, felt pretty cheap, especially with no radar.
Control definitely had better controls that Alan Wake, ye gods, I loved that game but it was wonky to do anything.
Yeah, I'm often frustrated by the "invisible enemy" in many games too, but in discussing it with friends, I've realized that some genuinely enjoy the "jump scare" thrill of it.
