In Doodle Jump, the aim is to guide a four legged animal called “The Doodler” up a never-ending series of platforms without falling. The left side of the playing field is connected with the right side. For devices with an accelerometer, players tilt the device from side to side to move the Doodler in the desired direction. Players can get a short boost from various objects, such as propeller hats, jetpacks, rockets, springs, trampolines and invulnerability shields (some levels only). There are also monsters and UFOs that the Doodler must avoid, shoot, or jump on to eliminate. Aiming is performed by tapping on different parts of the screen, on the Android and Windows Phone versions of the game there is also an automatic aim mode. Depending on the game mode being played, projectiles may fly in a straight line off the screen or be affected by gravity and fall downwards. There is no definitive end to the game, but the end for each gameplay session happens when the player falls to the bottom of the screen, jumps into a monster, gets sucked into a black hole, or is abducted by a UFO. Players can choose from several different themes including Original, Christmas, Halloween, Rainforest, Space, Soccer World Cup, Underwater, Easter, Ice Blizzard, Ninja or Pirate. The themes change the look of the Doodle Jumper, his enemies, and the background. In the Ninja, Halloween, and Easter modes, the player can buy new skins and extra lives with coins that can be earned in gameplay but may also be purchased. Furthermore, the player may enter the names of one of the Pocket God pygmies and the Doodler will turn into one of pygmies. Alternatively, the player can enter the name “Bunny” and the Doodler will wear a bunny suit, just like the one in the Easter stage.
There are also two other separate apps for iOS, Doodle Jump Christmas Special (a new Christmas theme) and Doodle Jump Hop, (a new Easter theme) where the player character is E.B. from the movie Hop.
A free version also exists. This version is nearly identical to the original, but features such as UFOs are not present, advertisements are shown and there is a limit to how high the Doodler goes.
Doodle Jump has received favorable reviews from critics, with TouchGen mentioning the fact that the game is ‘fun as heck’ and also praising the sound and cartoon graphics, which they feel give the game charm. The review ends by saying that the game is a ‘joy to play’ and that it’s obvious that a ‘lot of love went into this game’. Tom Love of Pocket Gamer called the game “unbelievably addictive, immediately accessible, and enjoyable every time you pick it up”.
