Last Defense (itch) (Pixelydian)

Earth, or what is left of it,  is occupied territory. At least it was until the Mars diversion lured the enemy's armada away. As Earth's last defense you must rescue the engineers from their prisons and take them to the nearly complete shield generators. Every 10 seconds brings you closer to their return and every 10 seconds the enemy might send a scout or a fighter to check on their conquered world. Destroy them to buy more time. Complete your objective before the enemy armada returns to save the planet.

HOW TO PLAY

• Move with “W”,”A”,”S”, and “D”. You can move diagonally by pressing two at once.
• Press SPACE to use your thruster.
• Press ENTER to shoot. Shooting enemies adds 10 seconds to your game time.
• Press SHIFT to land on the ground and rescue humans.
• Land on shield generators to unload the humans and arm the shield.
