Bounden is launching next week on May 21 for iOS. The game is launching for Android as well, but they've had to push back the release as developing on Android is quite the challenge. There's a Vine that quickly shows how all the different phones on the market make it tough on developers, especially for small teams.
As for the game itself, we can expect at least two more updates after launch that will include more dances. The making of video here shows you details on how the team is creating the dances, otherwise go check out Jonathan Holmes video preview showing how the game works in real time.
