Swipe left and right to collect stars, which level you up to grow your sun. You can also collect planets that give you bonus points at the end of each run. Watch out for the asteroids throughout the path that can take away points. There are black holes that temporarily make you invincible and send you forward at hyper speed. This game also has an upgrade system where you can purchase moons and level up.
