Oooo a 3D game! Props right off the bat for that. This is a neat little concept that I can see takes influence from other games of this variety. Simple & intuitive controls, cool enemy designs, and I like how each level has a different color palette to it. The music assets you used helped to convey that sci-fi vibe you were looking for, but it definitely felt a bit too dramatic at times. My biggest critique of this game is probably the mouse sensitivity and control honestly, it sucks that it resets every time you respawn and it's overall not very fluid and responsive :( which is difficult when you have to aim pretty precisely with your gun. Otherwise I liked what you were going for here, and after some polishing it up a bit, it will become even better!
