Run through space avoiding any obstacles that come in your path.
Swipe up to jump over obstacles and onto platforms, swipe right while on the ground to attack aliens and rocks. Careful of the bouncing rocks though as they cannot be destroyed. While swiping right in the air you will float in the air for a duration, use this to get over the green gas or to avoid obstacles. Shipping down while on a platform or while floating, you will cancel the float or go through the platform.
Send challenges to your friends to beat your highscore, or compete with those on the leaderboard.
