Are you interested in building your own, iPhone or Android game, but don't know how to develop mobile software? Los Angeles-based GameSalad has just made it easier for non-programmer to develop their own, fully functional games. GameSalad said its flagship title, GameSalad Creator, now runs on the Windows operating system, allowing users to build their own iPhone, Android, and web games. The firm, which has only offered its software until now on the Mac, said the software is now available for free for download. GameSalad had released a beta of the software for Windows in May.
