Impossible Rainbow Road

A physics-based game that's easy to understand but hard to play. You'll fall frequently! Eventually you'll discover the beauty of jumping and the sneakiness of time-rewinding. The game can be played with one thumb in portrait orientation, or two-thumbed in landscape mode or on a tablet, or simply by tilting the device with the optional tilt control technique. * Tap on the left or right to steer. (Or drag your finger or tilt the device, depending on your chosen control technique.) The further to the side you tap/drag/tilt, the more the ball turns. * Touch and hold the clock-rewind icon to reverse time. * Touch the Pause button to pause, restart, or adjust the sensitivity. You can customize the level of difficulty: * Easy means a larger heavier ball and a straighter, wider road. Good for practice. * Insane means a light, jumpy ball and a narrow twisty road. The highest scores can be achieved here with frequent long jumps. * Normal difficulty is midway between the other two. When you get a new high score it's compared to other scores for the same difficulty level. You'll get an idea of where you stand with a message like, "You're in the top 10% of all players!" Like a leaderboard but without fussing with names. You can select your choice of background images and bonus sounds. You can also record your own bonus sound; try your own yeehah or woohoo! 更新内容： * Add device-tilt as another control technique. I like it! It makes the ball easier to steer. * Allow selecting the background images (skyboxes). Add several more backgrounds, including some cool NASA images.
