Try to shoot the UFO See how many times you can stop the Aliens before time runs out! Arrow keys to move. Space to shoot. If you notice a lack of stars in the background, you've reached the edge of the galaxy.
First a huge thanks you to @W_Trotter_STEAM who made the original, a great base to remix from. Second a thanks to Scratch, makes this possible... and Third a big thanks to you for Playing, Thank You!!! Update: Now you can't just keep shooting once it's disappearing and relocating. :) Also made hyperspace. In this remix I tried to improove the grapics and added some sensing features.
