Alright, I have three critiscisms
For starters, the game looks, at best, unmemorable, and at worst, extremely ugly. Its immediately apparent (at least to me) that this is an Unreal Engine game. UE5 isn't bad, its my favorite game engine, but the visuals feel way too engine-defaulty. Try working on the atmosphere or post-processing effects some to make it stand out more. Its also extremely dark but you have a flashlight so I guess that solves it? I'd just prefer some more natural lights
Secondly this just is not fun. The enemy AI isn't bad, at least not noticeably so, but they're all extremely fragile. The Shotgun is also way too overpowered to be your starting weapon. You're in mostly tight-corridors and it can two-shot almost every enemy from a mild distance away. It resembles a Double Barrel (and is called the Super Shotgun in the menu) so I'd expect it to be strong with a very short range. Maybe introduce the Auto-Cannon first and have the Shotgun be an item obtained later.
I was also able to get the Rocket Launcher and Grenade Launcher without actually picking them up by holding Q, and the Grenade Launcher could be fired without ammo.
Thirdly the layout is bad, after going downstairs in the cargo-area I was completely lost and gave up. The item pickups are a little dim as well. Maybe try lightening them up and making it more obvious where to go with visual cue.
I can see massive potential, but as it is I would never consider buying this
