Brightside Entertainment has released Marble Arena 2 ( for Mac OS X. It’s a family friendly, physics based, free 3D marble game with a built-in editor for creating custom levels.

The game features 50 levels where players will test their skills on several types of surfaces, attempt to master a multitude of physics contraptions and go toe to toe — and sometimes toe to multiple toes.

Making it through all these perils in one piece, and  in time, has its benefits. Players will be awarded upgrade points for doing so, points that they can use to improve their skills or unlock their favorite from a multitude of marble skins.
