Press the up arrow to fly upwards. Your ship is a giant brick, so it will fall really fast when the up arrow isn't pressed... Also, you can use the left and right arrows to turn left and right, and use space to fire lasers. Try to avoid the bricks, because they will make your ship heavier when you touch them. To avoid them, use left & right arrows, or shoot them. Touching the edges of the screen will kill you.
This is another high-score game!
