can't figure out the piano puzzle, and does the hashtag symbol next to the heart mean anything?
I can give you a bit of hint:
Yes the hashtag symbol next to the heart is a “sharp” in music! So it means the black key to the right of the “heart” key.
And the piano puzzle is the last puzzle. You’ll have to gather all the symbols from other puzzles and find the sheet music before the piano puzzle.
Hope this helps and feel free to ask me questions if you’re still stuck. Good luck :D
