Ashura Blaster was released in March 1990.
Developed by Visco (on the 2nd stage you can see tiny 'Visco' on a large battleship).
The kanji characters on the titlescreen read 'Ashura'. Ashura is a demon related to fighting.
The game forbids the initials 'SEX' on the high score table. If you try, it gets changed to 'REX'. 'GKS' initials are also broken and are changed into 'GKR'.
