About This Demo

Get the ball to the flag. Build your own way there.

A sheet of paper, a ball, and a few mechanisms to play with. Place a plank, press play, and see if your idea holds up.

Change your mind while the ball is moving

Keep placing, moving, and erasing during the simulation. Add a last-second bridge, change an angle, or clear a path just in time. Run Again keeps your ordinary construction and restores blue stars so you can choose abilities again. Start Over resets the whole level. Undo and redo make experimentation easy.

One choice can change the route

Collect a blue star and choose an ability for the situation: jump upward once, shrink through a narrow gap, briefly fall upward, or draw a piece of the route. Pins, springs, sticky obstacles, and multi-floor layouts arrive gradually, giving the same page more than one solution.

Build your own page

Arrange the start, finish and mechanisms in the level editor, then enter playtest to try your route.

16 levels. The complete first chapter.

This demo includes all 16 levels of Rolling Start, from your first bridge to pivots, jumps, return routes, and chained mechanisms. Play with a keyboard and mouse in English or Simplified Chinese.
