IBalls is a physics based multiplayer game which has been created by a group of computer science students from TU Dortmund during the course “Digital Entertainment Technologies”. The game consists of a central arena and several minigames which have been designed with Articy Draft and later been implemented with Unity3D.
Every player is represented by a ball and one of the tasks is to push another ball into one of the many wholes (so that a minigame is started for this player). In the arena, there are several power-ups that change the physics of the ball avatar e.g. into an iron ball or an exploding ball.
For game design, the tool articy:draft was used in order to model the structural flow and visual appearance, see some pictures below:
