Yeah for sure that boulder hint seems to be too vague...17 is actually the sum of 1 + 4 + 5 + 7, so you have to move those boulders only, in order to make it work. How did you come across that pass through error? I'm having trouble re creating it. 

Yooo!!! I was super excited for this game. Congrats on your release! I know it's gonna knock some socks off!
