Doodle Jump Space is one of the themes in Doodle Jump. The Doodler wears an astronaut costume and the monsters resemble robots and space aliens.
The Doodler also has a laser specific ammunition, different from most other modes. The rocket ships are much more common than in any other theme. The background is blackish-blue with stars, and comets often shoot across, but they don't affect the Doodler's jumping.
Many planets appear along the left and right of the screen, and they include a blue planet with lots of craters, a similar planet in a reddish color, a cheese moon, and a planet with wavy purple lines all across it. Farther in the level a blue planet with rings resembling Saturn is visible. After that, a green planet with craters is visible.
There are often situations in Doodle Jump Space that involve jumping on monsters instead of platforms.
