Destroy endless invaders from outer space, that are trying to take over the earth! To do that, use W and S keys or up arrow and down arrows to move up and down. Use space key to shoot. When a UFO reaches the edge, it's game over, and you got to restart. Restart by pressing the flag button. The score is in the top-left corner.
I used scratch wiki and forums for scripts. This is the first game I ever made, but only published it as the 5th game published.
