Ninja Action 2

Ninja Action 2 is one of the Arcade games here that asks for no download and no sign-up. Designed around touch input, and comfortable on a small screen. Catalogued as 1 player, jumping, ninja, obstacle, platform.

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.
