@Pratik Bhalerao I used the FDs as part of the solution, which I think is intentional. Spoiler I used a few to build a corral for when the ball fell on the white platform, then gradually worked the ball through the maze to the shack. It was harder to do than I initially thought.
@Дамир make any inspired-by level from Story Page from 30 to 40. Choose any of one and rebuild it with your idea.
