Galaxy Invasion -Plus-

Galaxy Invasion -Plus- is an updated version of Galaxy Invasion. It adds a few synthesized speech samples, the ability to pause the game, a changed high score screen and the option to turn off sound. However, the most important difference is that the screen flips vertically (i.e. the ship is now at the top of the screen and shoots downwards) after 50,000 points and flips back and forth for every 10,000 additional points.
