As you progress, the game will get faster. Get combos by almost hitting the obstacles. Each time you travel through the green laser to score, you will earn a number of points equal to your combo. Once you reach an 8X or greater multiplier, play more conservatively. Concentrate on avoiding death and getting as many green lines as possible. If possible get near misses on clusters of obstacles to get multiple numbers added to your combo count. Travel through the Black Hole whenever possible to collect your accumulated combo points.
