-I like that there's no ammo pool and the game uses magazines instead.
-The gravity when you fall down feels too low.
-Black-colored enemies on a mostly black background makes them hard to see.
-The overall gameplay feels good.
-I wish you could pick up partially used mags on the floor like in some tactical shooters.
-I wish there was a lean system.
-I wish you could adjust your move speed. (A walk toggle, or a float value adjusted with the scroll wheel like in arma.)
-It took me a while to finish the level because I passed in front of the red gate a few times before realizing it was the end.
-I like how the targets in the shooting range bounce around when you shoot them.
-The music is really good.
