Avoid Meteors, hitting the edge, and the white thing below, and no fuel. The red circle is a shield. shields make you invincible. The yellow circle is a gun. shoot meteors to destroy them. You have 10 seconds before your power-up runs out. When you move, your fuel lowers. collect fuel tanks to raise it again. The green bar is your fuel. The grey and blue thing tells you the direction of the ship. The game gets harder as it goes on. More meteors and more speed. Put your score in the comments.
