I changed quality to low, and still didn't enjoy the game. Dodging bullets is unreasonably difficult, jumping over them doesn't work because your enemy tends to aim upwards if you jump, not giving big enough gaps to dodge.
Close range combat got very annoying, enemies would punch you away quickly. Everything seemed to instantly knock you back if you got too close, which was annoying when enemies spawned right on you sometimes or when you ran out of ammo on a weapon.
Really, everything works, it's just not a fun game. The guns don't feel reliable, and you can't punch because your enemies knock you away easily. It's not slow, it's annoying and there's no awesome action that you'd expect from madness.
