I missed a bunch on the first run thanks to them not being very visible from the Sides. also wish I had a crosshair, but I'm generally absolutely terrible at aiming, so I took 20+ seconds anyway, wouldn't have been better with a crosshair I guess. I'm just too bad at shooters.
I understand that the gun mechanics with reloading, safety, and whatever else you're doing is probably the focus on this, but to me personaly it just felt annoying, having to press r, then e, then q until I'm at the desired shooting mode, only seeing feedback in the lower right corner ( I know theres switches etc. on the Guns, but those are on the lower right aswell.) Resolution setting in options does nothing when in fullscreen.
Still, had fun blasting all my ammunition into the walls. The Clink when actually hitting something also was quite satisfying.
