I used to have this Android game that went like this: you had a tiny little purple bubble in a field of numerous other larger and smaller purple bubbles. It was you goal to 'eat' smaller bubbles to become larger yourself, untill you ate all the bubbles of the field. You couldn't touch larger bubbles or you would be eaten, these were green when being larger than you, and became purple when being smaller. The whole game had great graphics and this purple-ish galactic theme going on with cool flowy music. Because it was such a well made game I figured someone must be able to recall the name of it. Thanks!
