Hi,
I made an open source Flappy Bird type game using Unity3D. It is available for iOS, Android, and Windows Phone 8.
Traverse the skies and evade the brick walls in this arcade classic.
Modeled after Flappy Bird, this is an open source project designed to teach aspiring game developers how to use Unity3D to create multi-platform games.
