ReWrite

Build the board, press play, and watch the thing you built run itself.

Three rules

1. Every part in the tray must be placed. Not most of them. All of them.
2. The exit will not open while a single gem is left on the board.
3. Hit a wall or run off the edge and the attempt is over. Reset costs you nothing.

Controls

• Click or tap a part, then a cell, to place it. Tap a placed part to pick it back up.
• Space — run / pause
• → — advance one step at a time
• R — reset the board
• Esc — pause menu

Fully playable by keyboard or by mouse or by touch. Colour-blind palette and a reduced-motion toggle are in the settings.
