Make room.

Sometimes the way forward is back.

The goal

Bring the three pieces together. Drag one to begin.

Drag empty space to look around. Nothing moves until you do.

How it works

Each piece has its own path through the same space. Follow its dotted line in either direction. When another piece is in the way, make room for it.

A piece can be in the right place at the wrong time. You can always move it back, even after it fits. There is no timer and no penalty for exploring.

Select a piece below or press 1, 2, 3 with the scene focused. ← / → move it along its path. Use the buttons below for the same action without dragging. WASD orbit; Home resets the view; Z undoes a move.

“Back” moves away from the assembled shape along the path. “Forward” moves towards it. If a path looks edge-on, change your view.
