In my opinion, the game has four main problems
- The kills don't feel like kills.
Kills are not satisfying. Because the characters die easily and quickly.
For ourselves too, campers can kill us easily without having a chance to react.
Suggestion
Make the characters harder to kill.
- Guns recoil.
Suggestion
Increase the recoil a bit.
- Lighting.
In some places, the brightness hurts the eyes, in other places, it is hard to see. But overall, the game looks dark, you can't even see your character outfit clearly.
Suggestion
The lighting of the game really needs to be adjusted.
- Sounds.
Some sounds need to be adjusted or improved, for example footsteps sound.
Suggestion
Adjust and improve the sounds.
And one more suggestion
Add cooldown to the rolling.
