Mobigame has released an update to its popular block-rolling puzzle game Edge adding a new 3D engine and Game Center integration. With the new engine the latest version of Edge now runs a full 60 FPS and users can sync progress between their devices using Apple’s Game Center. The update also includes graphics optimized for the Retina Display and iPad 2 multisample anti-aliasing along with optimizations for older first- and second-generation devices. Users can also now play against a ghost block and several bug fixes are included to improve playability. Edge 1.7 is a universal app and is available from the App Store for $3.
