Drawn To Life was a pretty innovative game that allowed you to draw your own character and bring it to life. Hence the name and all that. Sketch Quest is similar - it allows you to draw things. And it's all wrapped up in a gorgeous art style.
The things you draw don't really have any real affect on what happens in the game, but it's a fun gimmick, and one that fits seamlessly into the game's incredible aesthetics.
Give it a bash.
