I'm stuck in Room 10, "Sound"
Any help? I have ABSOLUTELY no idea how to solve this. The hint doesn't even help.
"Sound" uses the game's note block system where if you right-click the note block, it plays a note at a particular place in the range, but that's not what you're dealing with here. You're focusing on the fact that the note blocks play the same note as a different instrument when you place different kinds of blocks under it.
The idea here is that when you open the trap chest to get a book, it changes which block type is under your "tester" note block. (On your left) You use the tester to figure out which types of blocks are under each of the note blocks in the "Sound" sequence and use the cypher in the book to figure out the numbers assigned to the block types.
You use the order of the block types under the "Sound" sequence to determine the order of your decyphered code.
