I really enjoyed this one. You nailed the aesthetic.
All the little nooks and secrets were well placed and paced. Environments are varied and interesting to look at. I do wish there were more sound effects, particularly footsteps, right now there are not enough noises for it to feel finished and living, but there's just enough that it doesn't feel silent and unnerving either.
In the opening I think a mouse sensitivity slider in the pause menu and making the crosshair highlight when over usable objects would go a long way. Everything once the game starts is great though.
Small thing, but it'd be cool if the username you enter showed in the chat box when you typed, my chatbox just had a colon and what I typed with no name before the colon.
