Just wanted to say my six-year-old and I loved this game . Only had two parts we got stuck on, getting the cube to the apse (which was clever), and figuring out two of the colors after that (couldn't figure out a clue/hint for 2 and 8, so we guessed it was the one color not used).
Great game, though! Even though it's a linear thing, my son already wants to play it again.
