So this was definitely an interesting game. Some of the puzzles took me forever to figure out (especially the last one, which I was totally overthinking). If you continue work on this game after the Dare, I'd suggest a couple of things. 1: If you really want this to be horror, one of the best things you could do is have the music change as the player progresses. The happy-go-lucky elevator-esque music doesn't really work well for raising tension. 2: Change up the rooms just slightly, especially at the beginning, or make the rooms part of the puzzle.
Fun game, I'm looking forward to more of your work!
