Here is some feedback I didn't see on the forum yet. It is gameplay related.
Headglitch (being able to fire at an enemy that can only see your head) is possible in the current state of the game. I don't think it belongs in the game as it is not realistic at all and is quite frankly annoying. In PUBG for example, if your gun is pointing to the wall you'll shoot the wall. You need to make sure that the bullets fire from the gun and not from the player's camera.
About mouse movements: sometimes when we move the mouse, it's not the screen that turns but the gun (video : https://www.youtube.com/watch?v=gkltX6fxYSk). I understand that this might be on purpose but it's screwing muscle memory and feels very bad. I think this should be removed. The fact that the gun doesn't always point at the center of the screen is not a problem though.
Keep on the good work
