**Playtesting:**

	- Since this is a multiplayer game, chat and private messages are a plus.
	- Spawning immortality makes spawn camping impossible.
	- A different map for each match increases the dynamics of the gaming experience.
	- Considering this is an FPS game, it is good that the game has enough obstacles on the map.
	- Lack of feedback in the menu (friend request and invite).
	- Spawning too close to other players occasionally.
	- The possibility of "jump shots": A shot during a jump is accurate only if the player was standing before. So, it is possible to stand behind an obstacle, jump up, and shoot while the opponent is at a disadvantage.
	- After leaving the ladder, the player cannot shoot for a long time.
	- The shotgun is too weak (even in close combat).
	- The weapon movement based on the camera rotation looks interesting, but sometimes it is distracting.
	- One can use [Match] chat even if he is not currently in a match (and this chat corresponds to a previous match).
