Thanks for giving it a try! I really appreciate the feedback. I think we want to put a little more time into this little game so hopefully we get the time to improve it.
Right after submitting, we realized that Duckley doesn't tell you where to bring his disk. There's a big crystal to the right (and kind of forward) of the dragon skull you bring it to. As for Frogsworth, I realize that his disk is a bit against the pattern. It's actually outside his area and south a bit. If you decide to give it another try, this should help you finish the game! Thanks again for giving it a try :)
