Considered as a hack of "Galaxian", this game seems more like a hack of "Moon Alien Part 2" by Nichibutsu, but with the graphics changed to look more like "Galaxian". This explains why the shots move with the ship and why the fuel gauge is there. On Moon Alien the shots move left/right but there is no fuel gauge. Galaxian also didn't use a 'title screen' formed with graphics, it went straight through to 'We are the Galaxians'.
