I had a lot of fun making it so I'm glad you found it enjoyable to play! As for that puzzle, I'd rather not give the answer straight away, but I hope it helps if I say that the temple is an upside-down layout of the overworld (hence the "turn back" part of the riddle). Then the "run home" part is... well, the theme involves "diamonds" and "plates". Once you figure out who's on first, the rest should come naturally. I may have made it a bit too harsh in that if you get the order wrong, you need to remove all the plates before trying again.
