Pet Subway Surfer

Open Pet Subway Surfer and you are playing — an Arcade game that runs on the page rather than beside it. Designed around touch input, and comfortable on a small screen. Catalogued as 3d, animal, avoid, html5, run.

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.
