Turtle Ninja

Open Turtle Ninja and you are playing — an Arcade game that runs on the page rather than beside it. It is built for touch, so a phone or a tablet is the natural place for it. Its tags here are 1 player, 2d, adventure, arcade, fly.

It is drawn for a tall screen, so it fills a phone held upright rather than a wide monitor. Close the tab and come back later; the game is still one click away.
