Meet Doodle Assault for Android (download), a quirky side-scroller that strays from the typical spaceship-versus-aliens shoot-'em-up style by incorporating some childish humor into its plot. In this game, you are a lone paper airplane, flying across an infinitely long landscape of doodled-on binder paper. Your enemies include snout-shooting flying warthogs, winged pencils, and other fantastic classroom doodles come-to-life.
As you destroy enemies with your tiny origami shooting stars, you can pick up coins that can be used to upgrade your plane's speed, weapon, health, firing rate, and defense. And the best part is that you get to keep all of your coins and upgrades even after you lose a life or get a game over, which is a heck of a lot more fun than starting from scratch every time.
Doodle Assault is a free download, available now in the Android Market.
