to clear the 2nd part of cannon puzzle. there is 4 roads on each side (+ the little block on the left that isn't a road), lets call them Left 1, 2, 3, 4 and Right 1, 2, 3, 4 from the top to bottom. First from the beginning, Exit from Left 1, Enter Right 4, Exit from Right 4, and Enter Right 1, then go to the cannon. That should solve the puzzle.
