Really nice, short game. I liked the writing a lot and the eerie vibe, and also the design of the different rooms (especially the subtle The Shining reference). The surprise moment at the end was very well executed, it got me good. My only feedback would be that the rooms felt a little large, and that I wish more would have been done with the photo mechanic (but I know it’s hard to have a lot of those moments in a short amount of time).
Question with a spoiler: With the infinite hallway, the only way I managed to get through it was by noticing that collision had been disabled for one of the walls, so I skipped the infinite trigger by going outside the wall and past it, was that the intended solution?
