This is a cute little game we made for Orange. The campaign was to publicise an offer that connected you better with your friends. So we made a game you could only play co-operatively. You each play alternate notes in a tune to make up the whole.
I first created a very basic version of the game as a prototype for the client to play. It had zero graphics, just blocks moving across the screen, but it could be played with any .midi file and the gameplay was a lot of fun.
We then worked with a games studio to turn the prototype into a fully functioning game.
