I have done some iphone and android development but most of my stuff has been done using cocos2d. I am curious what others would use to create a game that can go on android or iphone with little conversion that will allow me to create a simple 3d water balloon that "acts" like a real water balloon when the iphone/android is shaken to jump gaps or whatever. If I need to stick to one device it would probably be android and then iphone. Thanks in advance.
