This was fun! I really enjoyed how the atmosphere shifted mid-game.
Input felt a little glitchy here and there (I managed to get stuck in a garbage can and fall out of the map a couple of times), but I was able to play through to the end.
I found myself wishing I had more visual feedback for interacting and interactions. Most (all?) interactions had audio cues, but audio cues alone are easy to misinterpret the context of (particularly in the case of fuelling and activating the generator where there's time to walk away from the generator long before it's activated). I also would have appreciated it if the reticle turned into a hand icon when something could be interacted with.
Embarrassingly I fixated on the locks early on, but then completely forgot about them late in the game.
So far as the optional prompts go, I feel like this one maps well to "first person ____" and "atmosphere." Whether that was intentional or not, it's nice to see.
I want to note that some of the credits on your game page have multiple URLs within a single link. It would be good to fix those up so that each points to its proper URL.
I had fun with this one. Good work!
