Stickman Prison Warriors

Stickman Prison Warriors is a Puzzle game you can be inside of about a second after clicking. Taps and swipes are the whole vocabulary — a phone plays it best. Listed under 1 player, 2d, adventure, arcade, prison.

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.
