Gamelion's busy on DSiWare these days, recently announcing a release date for Furry Legends as well as the next game in its Academy series, Academy: Checkers. The studio made its name on DSiWare with Extreme Hangman, but on other formats its biggest hit is Doodle Fit. Guess what? That's coming to DSiWare too.
Essentially the game is Tangram-like affair: you must fully cover a silhouette with pieces of various shapes, all drawn in a sketchy "doodle" style. It's nothing to do with fitness, you'll be pleased to know.
Gamelion tells us the game is in Nintendo lotcheck at the moment and could see a release before the year is out.
