This is what we call a difficulty tweak: x5 more space +2 more enemies 200% more speed FULL-SCREEN OR DIE Instructions and boring stuff: Welcome to the year 3000! A race of malevolent aliens is attacking earth, and you are it’s only defender! Collect the green supply ships, and avoid all others. Be careful though, the Alien Mothership is approaching! (Scroll down) Instructions: you are the blue ship, use the mouse to move (Mobile friendly!) the green ships increase your score and health, and Rainbow ships increase health and score by ten. The Square ships are neutral and destroy supply ships and enemies, but hide a dark secret. The top number is your health, the second is your score and the third is the timer. Your Final Score is determined by how long you survive plus your score. You are doomed!
