Arcade Mode: In Arcade Mode, you must collect as much spheres of energy as you can while avoiding being killed by enemy ships. In order to find these spheres, your radar continuously calculates the x and y components of the distance vector between the sphere and yourself. You must correctly exploit this information to hunt it down. Once collected, a new one appears at a random location in space.
Survival Mode: In Survival Mode, there are no target objects to collect. You just have to kill as many ships as you can while surviving their deadly shots. The more time you spend without being dead, the better the score.
Fuel tanks and black holes are also found in the cosmos. You can share your score via social platforms.
