Free Android App - Doodle Jump

Doodle Jump( $0.99), by Real Networks Inc., is today's free Android App at Amazon. If you don't yet have an Android phone or tablet, there is a way to get an emulator on your PC, so that you can get the Amazon App and the games. See the comments on this post for now and I'll try to put together a step-by-step primer for a post later on (it's a bit involved, but doable).

Book Description
If there is such a thing as a "classic" in a mobile gaming genre that is still very young, Doodle Jump is exactly that. Millions have been charmed by the delightfully addictive gameplay and irresistible style of this casual platforming game.

Nowhere to Go But Up
The object of Doodle Jump is to guide the Doodler, an adorable, interminably hopping four-legged creature, up a series of never-ending platforms. Watch your step--miss a jump and the Doodler will fall to its doom. Some platforms are solid and steady, while others move, explode, or have other properties that create interesting challenges for the Doodler.
