Blast Off was released in March 1989 in Japan.
Even though the game is the sequel to Bosconian (which used a synthesized, DAC-generated voice saying "Blast off!" at the beginning of every round), Blast Off had more in common gameplay-wise with Namco's own Dragon Spirit than with Bosconian; this is especially noticeable in the third area of every world, where the player's ship undergoes an increase in size, and must destroy a boss. Despite several gameplay differences, the connection with Bosconian was emphasized in the marketing of the game, with the hexagonal space stations from Bosconian appearing in Namco's press literature, the game's title screen, and in the game itself.
The game is also worth noting for its usages of various "Engrish" phrases, such as "To push start only 1 player button" (on title screen), "Go next" (at end of world), "Congraturations" (at end of game) and "Entry your name" (on high score table). There are a total of six worlds in this game, and each one has three areas (so there are a total of eighteen "stages" to play through).
Victor Entertainment released a limited-edition soundtrack album for this game (Namco Videogame Graffiti Vol.10 - VICL-40097) on 16/12/1993.
