Concept: I was not expecting an idea that wasn't even originally for this theme work this well with it, but it's great.
Gameplay: it's super engaging, I really liked piecing together the stories of each ghost while trying to tell their intentions. I felt like some conclusion like a game over or bad ending if you let bad things happen was missing, though I can imagine it was planned but couldn't fit in the timeframe.
Art: amazing aesthetic, I love the fake OS style, it's always so immersive and spooky. Also very polished stuff, everything fits together perfectly.
Audio: as with art, super polished stuff, fits the vibes really well.
Very impressive stuff overall, you always nail the spooky vibes these jams. I also think this genuinely could be developed further to a full fledged indie horror game, the potential is absolutely there. Amazing stuff, nicely done!
