-In the first room, I ended up looking at your script and map because I couldn't figure out how to get through the door. I didn't notice the shovel in the corner (although maybe I just wasn't being observant )
-both the meat and the dagger had no name or description when I picked them up. It simply said "Picked up ".
-I found a door that wasn't placed properly. It was in the room with the painting canvas. (took a screenshot for you: link)
-the monster killed me and I re-spawned only to find that the door leading back into the room (room with level door and closet) was locked; I had to restart. I'd suggest adding a checkpoint in that room somewhere.
-after getting through the door where the monster came from, there was no where left to go so I assume that it was the end of the demo?
Other than that it had good atmosphere, and the story is intriguing. I'm excited for the full version!
