Great game overall! I only have a few nitpicks. First off, after freeing the worker on my first playthrough, there wasn't really anything warning me not to keep investigating so I kept investigating and got lost. For games like this, I like it if there's some sort of foreshadowing when it comes to non-obvious loss conditions like that. A line in that passage telling me "You can see the tunnel lights go out up ahead" or "you think you can barely remember the way back" would have been appreciated. The fact that the maintenance worker kept running into the tunnel baited me into thinking there was more to do there, so the instant loss felt a smidge unfair, especially since it doesn't seem like there's any way to save that NPC. I did like how you gave me the option to gather some information by talking to the NPCs before committing to any decisions, and I loved the general noir vibe of the game. The game's a bit small, but besides that one thing with the maintenance worker, I liked it! Good game.
