When a planet is close, press & hold anywhere on the screen to tether into orbit. (Space works too.)

Let go to fly off along your current heading with a burst of speed. Point it at the next planet.

Skim close to asteroids without touching them to score and build your multiplier. Three strikes ends the flight — so does falling off the bottom.

The screen banks a little with your sideways speed. Fly straight up, or orbit, to level it. Press T (or use Level Lock in the pause menu) to hold it level.
