Jelly Escape

Jelly Escape is listed here under Action. There is no launcher and no install between you and it. Taps and swipes are the whole vocabulary — a phone plays it best. Catalogued as 3d games, action, avoid, boy, boys.

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.
