Thats funny because I felt like it was a port because of the horrible control scheme. You cant move slower, so you have to tap keys to move slowly, but tapping keys does dashes, exactly the opposite what you would want. Dig around some conf files to fix it. Crouch button is c, but it doesnt work during dialogue, even if you rebind the dialogue skip button that is also c by default.
Its like nobody playtested it at all on PC
