First of all, good game. Second of all, I have re-tread every room in the game multiple times, scanned every patch of rock and woods with the camera for secret paths, done all of the dev secrets, and I know that the lantern sparkles near collectibles, and yet I've been stuck on 41/42 crystals. Yes, I found the one in the West Woods cave. PLEASE help, I am literally dumbfounded by how I haven't found it yet....

I’m in the temple room with three organs. I’ve worked out by accident some of the notes that make the kalimba glow, but I have no idea how to finish the song or how to proceed. Can someone help?

Amazing game! The atmosphere makes it worth wandering around. But I've been looking for the last crystal for solid couple hours. Any tips you could give me on finding it? Also could I have missed it in one of the gated locations, or do any missed crystals appear in front of the gates after you've finished the area?...

in a separate post for easier editing.

I am playing on the keyboard, the instructions to get wind have a /5 at the end, I have no idea what that means, am seriously stuck, the string of numbers are fine until that /5
