About This Game

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.

A blue star can turn the same page into a new route

Collect a blue star and choose an ability for the situation: jump upward once, shrink through a narrow gap, reverse gravity for a moment, send another ball from the start, or pause to draw a solid line that catches the ball. Bounce, reverse, and extra-plank choices can reshape the route too.

Build a page, then play it yourself

Use the level editor to arrange the start, finish, planks, and mechanisms, then enter playtest and see whether the route works. Pins, springs, conveyors, sticky hazards, and multi-floor structures can be combined into different physics puzzles.
