The classic arcade shooting game style pioneered by the likes of Gallagher and Space Invaders gets a refreshing makeover in A Doodle Flight. Players have to create and draw their own battle-ready spaceship before they can wage war on the enemy crafts. Instead of sleek mean fighting machines, players attack cute hand-drawn enemies such as penguins, angry clouds, stars and fish.

Charadium
Charadium is an online multiplayer drawing game that closely resembles Pictionary. The game is played with two or more people online (so you must be connected to the net via WiFi, 3G or Edge to play). One player is presented with a word and has to try and convey its meaning to the other players using only their drawing skills. The other players have to try and be the first to guess what that word is.
