Thanks for the comments Ilya!
The art concept kind of had to go out of the window, together with half the game 😅 Originally I had an idea to keep characters and enemies in a low poly style to give player a hint of what's real and what is a decoration, as the amount of bullet was supposed to be finite and player was expected to be in situations where they would need to think about what is appropriate to shoot (like some decorations would be moving, but they would be not that well visible in the darkness). But, since I had to gut a lot of stuff, I didn't end up executing well on this idea (or perhaps it just wasn't a good one). I am thinking of implementing the stuff I didn't manage to after judging ends, but for now I added hit sounds as a quality improvement, as there is a hit animation on zombies, but my whole animation state handling is somewhat janky and should be reworked, so perhaps you ended up not seeing it on your end.
