The character moves too slowly, and the game's not really scary, rather boring.
But after the "Day 5" it started to get interesteing at least.
If you want to achieve proper psx style, then dont just use doom style decorations and low resolution. Also use affine texturing and low quality textures (128x128)
And the table's texture it strechy. ( I wont blame you if you dont know modeling )
Overall it's a solid effort. I wish there was more though, the ending feels rushed.
I might sound like an a-hole but I just wanted to adress everything that's wrong with your game,
so you can improve.
