I thought the gun was some kind of stun gun at first just because of the SFX and the low damage. Also, the text at the beginning went by a little fast. It should probably also not play every time I retry. I know it said press any key to continue but that didn't work; I assume since it automatically went away that you had some issue and made a last minute mend.
You placed loot past a lot of enemy crowds, I assume because it was meant to be replenishment for the player after using up their resources but for me I was already out and had to run past the enemies to get the ammo before turning around to fight them.
You can kind of just run past the blood pools. I wonder if maybe making the enemies drop loot would better encourage fighting them. Like a risk vs. reward thing. Also, there was some kind of bug with the aiming where my character will just stop responding to my look input sometimes for a tiny amount time.
The level, while a little bland, was still aesthetically pleasing. I like having to knife them when I'm low on ammo. Overall a pretty cool game.
