I completed it too. Cool map, I liked the story twist at the end. I wasn't really scared though but the monster startled me a couple of times (it almost killed me once haha).
The music in the cellar was annoying. Too much key finding, but at least there were some other puzzles later. Some rooms felt like they just had objects placed randomly in them, that didn't feel realistic. Some Mementos would have been nice... felt a bit lost a couple of times. Still, it was a good map and I had fun playing it.
PS. You spelled Design wrong in the credits
