Galaxy Electronics Corp. - Space Invaders (19??, LED, 9 Volt, Model# ??)
This game looks like a one-player only version of their Galaxy Game 2001. It's probably a game that's been released by another distributor, but since it actually says '2001 Galaxy Series' on the box, I'm assuming it's made by Galaxy Electronics (and it looks almost exactly like Galaxy Game 2001). The game is timed, and there's a difficulty switch that determines the amount of time you have to play. Galaxy Electronics Corp. was a company based in Taipei, Taiwan.
