Fidi is a fresh take on an old idea. The aim of the game is to get the highest score possible which can be submitted to the worldwide leaderboards. Fidi is an ad based free-to-play Flash game and a low cost iPhone game, with specific changes between the platforms. The Flash version has two different control modes, and implements Mochi Ads and Mochi Social for leaderboards. The iPhone version was designed ground-up for the platform, and is controlled completely via the accelerometer, it implements the OpenFeint social system and is advert free.
