For being only a short little demo, this seems really promising so far!
The demo was a bit rough at least for me. Nothing in the game broke as I was able to go all the way through it and complete it. But the game has glaring performance issues that the graphics themselves really do not reflect.
The game to me looks like a unreal engine 4 game from like 2020 somewhere around there and the game would have these massive frame dumps that somehow ended up affecting my recording software. Changing some shadow/lighting setting did mitigate the vast majority of the frame rate issues, but issues did still crop up at least when the game had to load in something. So the optimization does need some work but aside from that the plot is really good, the story, graphics, sound design. The scares/staging was really well done as well and I loved the build up. The section where you get chased should be reworked as I stopped moving at one point to let the ghost patrol away from me, and the ghost saw me somehow even though I didn't move from the spot.
Overall though this game is solid and seems really promising! Made a video on it.
