Flappy Turtle

Flappy Turtle is one of the Clicker games here that asks for no download and no sign-up. It is built for touch, so a phone or a tablet is the natural place for it. Its tags here are adventure, bird, flight, fly, ninja.

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.
