Very nostalgic and funny entry! Feels very inspired and I quite enjoyed all the inclusions of extra dialogs that were entirely unnecessary :) I really enjoyed hearing Otto blather on each time I came through the room. Every character had the right dash of twisted humor, as did all the puzzles. The voice acting was all perfectly executed and suited to each character.
I had to watch a video to get a couple things figured out, mainly the ventriloquist puzzle and I didn't notice the iron was an interactable item. Maybe when using the ventriloquist book on the horse skull (which I tried many times) the player could be given some kind of hint about using the book on the bookshelf. Great entry overall, maybe the most polished and funniest I've played yet!
