Very Long Dog

Very Long Dog is the snake game, except the snake is a dachshund called Noodle and the apples are biscuits, sausages, tennis balls and a slipper, all of them with faces and all of them thrilled to be picked. Steer him to a treat and it hops on his back and rides along, waving, while Noodle gets a bit longer. Bump into yourself and nothing terrible happens: Noodle ties himself in a knot, loses a little length and carries on. Every knot costs one of his five bows and the fifth one ends the run, but a new page gives one back.

He keeps growing, and the world does not. When he is too long for the living room, the page zooms out and the living room becomes a small square in the back garden. Then the garden is a patch in the park, the park is a block in the town, and the town is a dot on the Earth. A note on the page keeps track (the dog is now 4 km long) and the score grows at roughly the same rate, which is to say unreasonably. A run is quick, a couple of minutes, and it ends with Noodle wrapped once round the whole planet, nose to tail, in a bow.

Run out of bows before then and Noodle becomes a present instead, which he also thinks is great. Every run, even a knotty one, ends with a new hat until he has all four, saved in your browser along with your high score. There is a button on the title page that says do not press. If you press it, Noodle gets more legs.
