Good game!
+ I like way you've done the startup screen.
+ Player's body movement when moving the mouse is good
+ I didn't notice any lag.
+ Death animation looked good.
+ Blood and red screen worked well.
+ Crosshair gets less precise while you shoot.
+ No crashes here.

- There's multiple minor bugs that aren't horrible but stop it from being perfect: I once had the sound of someone elses weapon every time I shot, the kills aren't always displayed right.
- Please leave the chat messages visible. Don't delete them. I never had time to read them cause I was busy killin... and they were gone by the round was over.
- I really don't like how the player moves. I felt like I was hovering, the feet slide, the shadow's weird, the animation is too slow and the strides too long. Also, the footsteps sounded too loud and too much like there was an echo.
- I wanna be able to crouch to get more precision
- It doesn't pull back when I shoot. The crosshair gets less accurate, but there's no recoil.

Overall it was fun. Gameplay was good. Well done!
