Sorry for the silence lately guys, but we have a huge announcement to make; Overturn is going Windows 8 ONLY! With the success of Windows 8 lately we've decided to stick with Windows 8 and drop all the other operating systems we had planned for porting Overturn to. To announce this update and major change, we've designed a whole new theme to fit in with the rest of the metro Windows 8 apps. Tell us what you think in the comments!
