The Sketch Nation is a new and original iPhone arcade app that allows you to create your own custom shooter game from scratch. To create the in game sprites you simply draw your character on a piece of paper and then take a photo. Import the sprite into the game from the iPhone photo album. Check out the video after the jump for a full demonstration.
Sketchbook (and similar drawing apps) can be used to create assets for the game, but it is not recommended to use them for creating levels. Levels need to be at least 1200×1600 resolution to look proper in the game.
Check out more videos of games created with Sketch Nation here.
