Dot and Dot

Dot and Dot runs straight in the browser. It is filed under Puzzle, and it loads on the page you are reading. It is built for touch, so a phone or a tablet is the natural place for it. Its tags here are 1 player, 2d, block.

It is drawn for a tall screen, so it fills a phone held upright rather than a wide monitor. It costs nothing and asks for nothing: no registration, no download, no launcher.
