Pixel Invaders

How to play

• Move with left and right, fire with Space. One shot in the air at a time.
• The formation marches sideways and drops a row every time it reaches a wall.
• The fewer are left, the faster they come. The last one moves frighteningly quickly.
• The four bunkers stop shots from both sides, and wear away as they take hits.
• Let them reach the ground and it is over, however many lives you have left.
