Fold

A sheet of paper, a paper doll, and a flag pinned to the far side. You cannot walk there. So fold the page: drag a line across it and the half you are not standing on lifts, turns over, and comes down on top of the rest. A far ledge folds into a bridge. A tab of paper folds over a monster. A standing beam, creased on the diagonal, lies down as a step.

Thirty pages. Each one gives you a budget of creases, and unfolding does not give one back, so a page is a thing to work out before you commit. Finish inside the budget for a silver star; find a fold the page was not built around and it pays gold.

Play takes you through the pages in order with a checkpoint every four. Lose a page and you go back to the checkpoint. Or pick any page you have reached from the grid and practice it.

Runs in the browser on a computer, a tablet or a phone. Your progress is kept on the device.

On Ipad: if you swipe down it will exit full screen, swiping up works. For now this is the best option until I upload to the app store eventually.

Controls:

- Keyboard: A/D or arrows to walk, W or space to jump, drag with the mouse to crease, right-click or U to unfold, R to restart, Esc for the grid.

- Touch: thumb pads at the bottom corners walk and jump, swipe anywhere else to crease, and MENU / UNFOLD / RESET along the bottom edge.
