I really like the vibe of this. I got to the end and made a wrong choice so the game ended. I wanted to play through again to see the others but having to go through the two other stories first seemed a bit of a slog. Might be better if there was an autosave or something before the third story.
Game controls were fine - sometimes with games like this I prefer at least the option to just do everything with the mouse, but it makes sense and feels like good design to have the important parts (the choices) done with the other hand. It looks great. I'm not a fan of dark horror stuff but it has a strong atmosphere. I think you could maybe do more with the sound, not that it's bad.
The story made sense in the abstract way you're going for. The first mini story certainly did. The second seemed a bit random (choosing the cups) but still cool. The third one didn't make sense to me so much much (sudden mention of a base, and towns, and things I didn't really get) though I presume that's just part of the idea not to know everything, and like I said, I didn't get far into it.
It's pretty cool though. Well done!
