Its rough, really rough.
The camera is too close to the character so you can't really see him, and at the same itme the fov is very low.
Mouse movement works weird and it often glitched, enemies are spongy and very dumb, theres no lighting, the enviroments are MASSIVE with slow movement speed.
I think the problem is that it has 100 small issues which need fixing, and they pile on each other creating layer of issues.
For now, I would suggest the easiest changes to apply: Increase fov, make the camera be farther from the character, make enemies have less health and give them a longer detection range.
It has potential, but its still really undercooked
