This game is absolute quack. Very fun and addictive.

My only suggestions for the devs/ambitious modders at the moment are
-improve and vary the ambient sounds and soundscapes, especially when in interiors or just based on the surroundings, and also reverb/sound occlusion so sound properly carries, or is muffled, depending on whether you're indoors or outdoors
-more sounds for various actions, like having a character's movement sounds change based on what they're wearing/equipped with, or for doing things like mousing over items in a container/lootable, as if you're rummaging around in it
-idle/ambient dialogue for NPCs in the form of text bubbles, that are affected by how well you can hear them or how far away/close they are. sort of like what's already being done with them calling out reloads.
-improve the weapon handling animations, especially reloads, since it looks kind of strange the way they do it now

My first VR game, and that may have been a mistake because it's set the bar so ridiculously high for me.
My only gripes with it is that it's over far too soon, and is a bit lacking in enemy and weapon variety.
