Neat game. Music and sfx were great. I liked the slow narrative reveal.
Two small critiques -
I couldn't exactly place the setting. It felt like a bar to me(probably because of the pool tables), but I assume it's actually either a mental health facility(notes + wider rooms feel like rec areas), a hotel(red carpet, also rec areas), a surreal version of his family home(bedrooms and hardwood flooring), or maybe some amalgamation of all of the above. Probably only a few tweaks to clear that up if you were so inclined, but if you were going for something unplaceable then you're good. Idk, just a thought.
I didn't have trouble finding the keys, but you could maybe add a little light source around interactables/keys to draw a bit more attention to it. Or maybe they glow a bit brighter once player light hits them. I was checking every picture frame and book case for an "E" popup just in case, which maybe took a bit of the immersion out of it.
All around solid, though. Good work!
