It might be impossible, but it was fun to make.

Looks good.

Played a little bit. I suspect it is not possible. The ball loses speed on the way through the gaps, and there is not enough space to set up machinery.

One other observation: it runs slow. I guess because of the number of wood blocks.

    Over the top is tricky too: can't see how to give it enough of kick to the left to get started.

    Surprising that it's slow because the wooden blocks are static so should be relatively easy to calculate.

    levelsbot The hardest part was making the machinery thin and flexibile enough to fit with the ball.
