Doodle Jump is an enormously popular mobile game developed by Lima Sky and released in 2009. The game has since become a classic and is available on a variety of platforms, including iOS, Android, Windows Phone, PlayStation Portable, and Nintendo DSi. The main objective of the game is to control a character, known as the “Doodler,” and jump as high as possible through a series of platforms. The player must jump on platforms, avoid enemies and obstacles, and collect power-ups to reach the highest possible score. The Doodler moves up the platforms by using the device’s tilt sensors or touchscreen to move left and right. The game also features power-ups that can help the player progress higher and faster. Doodle Jump has received numerous awards, including Apple’s “Game of the Year” award in 2009, and it is still one of the most popular mobile games today.
