Hey saw you in the discord. The game is really nice, reminds me of flash games of olde. The piano puzzle is I think too difficult, perhaps not on purpose. Consider implementing it so the keys sound in order of a real piano and/or some player feedback to know if it the tune was entered correctly. Once I memorized the tune & plunked it out on that funky piano I still thought I was wrong for a few minutes before I just decided to go try the next room. Congrats on a nice jam!
