Alright, I played through it, and I'm here to give my honest opinion and hopefully valid criticism, so below I will explain what I liked, and what I didn't like.
Pros: I love the guns. The guns are well polished and don't feel sluggish to play with. Enemy design, I do like the designs, and as much as I would've liked more variety, the games only half an hour at most, so I can't complain. I especially like the weird Xenodogs, whatever they are.
Cons: AI, in trying to say this in the nicest way possible, the AI is dogshit. Enemies don't react to gunshot sounds, or walking, or flashlights, and walking into them from behind, they only look forward, and are always stationary unless chasing you, and often get stuck on the geometry. Level design, one thought I had multiple times while playing this was - why do I need multiple keycards just to progress? I may not be a game developer or coder, but I think when designing a level, make it look like something you'd actually see in real life. I doubt most security doors need 16 different keycards to open, and I don't often think the door will glow whatever color the keycard needed for it is. And don't stick enemies like soldiers and Xenodogs together, the story (that I can piece together) is that the creatures kill all humans, so it doesn't make sense why they don't fight the soldiers. And finally, lore. I know the game is super duper short, so I won't go too in depth in this point, but there's basically zero lore besides what's given after the beginning section, notes about how the crewmates reacted to the monsters would've been great. I didn't really run into too many bugs, there was one at the beginning after you pick up the shotgun, where if you go to your flashlight you can't equip the shotgun back, but finishing the first section fixes this issue.
I did enjoy my time with this game, however it does need improvement, I hope my review helps shape your future games in any way, and I don't want you to be discouraged by any criticism or negativity. I want to see more of what you can make, and I hope to see some amazing future games :)
