Doodle Jump is the game that defined the early iPhone: a four-legged scribble bounces upward from platform to platform, forever, and you steer it left and right. Platforms break, move or vanish; monsters and black holes appear; springs and jetpacks launch you skyward. Lima Sky released it in 2009 and it became one of the first mobile games to sell millions.
In the browser the tilt control becomes the arrow keys, and everything else is intact: the graph-paper look, the endless tower, the height counter that is your only score. Runs last a minute or two, and the leaderboard is a number that everyone understands immediately.
No. The tower is endless; the platforms get sparser and the monsters more frequent the higher you go. Your score is how high you got.
In the browser, the arrow keys (or A/D) replace tilting. Everything else works the same way as on a phone.
Yes. It is a very light 2D game with arrow-key controls that runs in the browser with nothing to install.
