Red star should be navigated to collect all the gems in mill-game like maze. Black Star is clever and wants to smash into Red Star. They go around in different directions. Red Star senses the real world gravity. Smart phone should be placed in player's hands, but on it's back, facing up. Navigation is performed by leaning of the smart phone in wanted direction before the crossing of paths, so that Red Star can slide into nearest path, or if smart phone is on it's back and there is no leaning, then Red Star stays in current path (there is an indication with the arrows in lower right edge of the screen, in which direction Red Star aims, because of the tilt). Only neighbouring paths could be crossed to. If all the gems are collected, there is a new level with faster movement. If you can not escape the crash, you can make Red Star invisible for a second, and thus escape death, but only 5 times in one game. This is performed by quickly taping onto Red Star. If you tap anywhere else on the maze, Options is displayed. There, you can choose your starting level (if you are bored with slow levels), choose to turn off the sound, and input current player's name. Hall of fame is displayed in the display with Maximum Scores. Enjoy!
