The objective of the video game Doodle Jump is to prevent the character known as “The Doodler,” a critter with four legs, from falling off of an endless sequence of platforms. The edge of the playing field on the left curves around to meet the edge on the right.

To play Doodle Jump, all you have to do is move from left to right in order to get to the platforms. To fire, use the left mouse button. The game can be played indefinitely, therefore to get the highest score possible, you need to stay in the air for as long as you can.

Doodles are simple drawings that can have a concrete representational meaning or may just be composed of random and abstract lines or shapes. They are typically created without ever lifting the drawing device from the paper, in which case they are typically referred to as scribbles. Doodles can have representational meanings, or they may just be composed of random and abstract lines and shapes.

The Doodler, or more particularly a list of Doodlers that scrolls horizontally, can be found at the very bottom of the screen. The list is numbered from one to eight, symbolizing the eight levels that are available in Doodle Jump 2; each level has its own introduction screen and writhing monsters.
