So I quite like this game, tho I think there are a few areas that could be improved:
I'd say enemies take a little too long to kill, with some taking 3 or so headshots, and more bodyshots. I'd probably change this, so that enemies only take 1 headsho, but a couple bodyshots, or something like that.
I also kept backing away from enemies, and I wish I didn't have to. If there were more oppertunities to play aggressive, and get in there, I think it'd work better with the vibe of the game. But as it is, if you stand too close to an enemy for more than a second, they kill you. So you gotta move in, hit them one, move away, move in, hit them, and repeat. If hitting, kicking, or shooting stunned enemies, or the player could take more than 1 hit, then this may not be a problem anymore.
As a smaller addition, picking up and throwing on the mouse wheel was odd, and something I never really got used to. I always kept trying to press E to pickup a weapon, for it to do nothing, until I realized I had to press the mousewheel. I'd change it around personally, but that's not that big of a problem really, tho it did stop my momentum from time to time.
Love the audio and the visuals, on that front the game is at it's best. Gameplay has a solid foundation in many ways, though there's places where some improvement would be appreciated
