Im liking a lot about the game and i want to give some suggestions: it needs options for mouse look sensitivity and control binding, those are fundamental for accessibility. also cant go wrong with a fov option. You need to figure out how to make sound play in stereo/3d, its important to know where enemies are without looking. The shotgun firing 5 pellets in such a wide spread is just bad, ether make it like 15 pellets and/or tighten the spread. You also need to figure out how to make the grenade not collide with the player, at least on its first frames of spawning
