I played the game, but didn't record it, as I suck at these sorts of games [Queen Faith is not alone in that :o], and mostly end up running 'round like a headless chicken [which I did].
1) the texture in the ride up [elevator, opening of game] is horrendous and should come with a warning [epileptics].
2) some of the bodies stick through/out textures. I don't know what you guys used, but in Maxon Cinema 4D, you make a body/surface rigid, so everything bounces off of it.
3) the ammo of firearms look all different. Little bullets for the hand gun, shells for the shotgun, and larger bullets for the machine gun. In this game, all bullets look the same.
4) readable texts are shown in white fonts. Against light background that's no that easy to read. Perhaps a [small] black glow around them, will make them stand out.
5) Most of the dead I've seen [way too many], had their eyes open [not all though], with the eyeballs rolled back [white only] and their mouth agape [if they died without anyone getting to it quickly to prop it up until rigor sets in - stiffening of the muscles], same for eyelids.
Having said all that, I agree with Queen Faith, your game has a lot of potential. My advise would be to hook up with the man behind Karantiin. you can find him @ https://karantiin.itch.io/karantiin
Or you can find him on Discord #karantiin
Good luck!
