Great little concept. I liked finding out what was behind the doors.
I would have liked some more feedback from some of the rooms. The one where you roll a dice against "them" was the only room where I got to see their choice (other than combat... but the combat rooms didn't have any real feedback either). Rock Paper Scissors would just say "YOU LOSE" instead of showing their choice. Etc...
Other than that, I had a lot of fun. It felt like exploring a series of mini games!
Nice work.

P.S. Was that God Rest Ye Merry Gentlemen?
