Ninja Jump Game

No download, no account: Ninja Jump Game is an Adventure game that runs where you found it. It is built for touch, so a phone or a tablet is the natural place for it. Listed under .io games, 1 player, action, adventure, game.

It is drawn for a tall screen, so it fills a phone held upright rather than a wide monitor. Everything runs client-side, so there is nothing to set up before you start.
