Giant Rush: Imposter

Giant Rush: Imposter is listed here under Arcade. There is no launcher and no install between you and it. Designed around touch input, and comfortable on a small screen. Tagged 3d, 3d games, avoid, boy, fight.

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.
