My favorite part of this is definitely the atmosphere created by the art and music, combined with the funky house layout. Getting lost is kinda fun, which is good because I did that a lot, haha. The various puzzles are clever, if a little obscure sometimes, and I especially enjoyed the piano part. I'm not sure there's a ton of replay value to the puzzles themselves (since the real challenge is just figuring them out the first time, after which you can do them pretty easily), but really I'll play this again just for the atmosphere and game "feel"
