I actually started the game twice, first time I got to collecting 3 floppy disks, but then I saw those paintings appear, and I said; "Nope! To Scary for me!"
But I collected courage and started it again, and played it through this time!
As Forild said, the ending was a bit strange, but you really nailed the scary atmosphere, great job with that!
The low resolution aestethics was really nice, it reminded me of old 90's game intros like Dungeon Keeper, Diablo etc.
Great job, really liked it!
