Very good game...Good graphics and sound. Wall jumping was a little difficult for me...character seemed to slide down a little too fast...but I was able to get past it with a lot of tries.
Yeah. I felt the wall jumping could have some improvement a bit, The Flood was giving me issues because of it and i felt the flood gets a bit too fast making it a endurance round.
Maybe try disabling the built-in controller support by pressing F3 and then using a program like Joy2Key to bind the keypresses to the buttons of your PS4 controller.
