offtopic: today my daughter played on lego.com some flash based games, when the system slowed down because of nod32, surprisingly a unity loader appeared for a moment.
okay.. free Android and iOS.. but.. many things are missing.. No Audio Filters No Video Play No browser Support Unity Splash Screen is fix and can´t be deleted No Occlusion
BUT It´s a good start for learning mobile programming. I really hope Acknex will start Android Support soon ^^
