Doodle Games is a popular mobile game in which players tilt their device or tap the screen to guide a character known as "The Doodler" through platforms. Along with boosters to drive your alien to new heights, obstacles provide an extra layer of difficulty to the gameplay. The first threat you'll face is brown platforms that break upon impact, but this is a minor issue. The most concerning threats are aliens and black holes. Make sure you jump cautiously. There are various ways to travel faster and increase your score in Doodle Games. The first option is to use the springs to propel your small alien higher. You'll also encounter rocket boosters and a propeller cap that will boost you further.
