Charge the ship by klicking on it while deciding the direction and start it by releasing it.

Click on the position on the screen you want the ship to fly to or shoot at.

Shoot by clicking on the ship when you are inside a crystal circle.

Break the crystals that share your ship's color to get the most fuel.

Use the crystals on the edges of the screen as orientation help, if you collected crystal parts that do not have the color your ship has you lose that help until you enter a crystal circle again.

Avoid hitting the walls with your ship on your way to the end of the level.
