(SAT) Fantasy Zone

Horizontal shoot’em up that introduced, with Twinbee, the “cute’em up” subgenre; arcade hit in the middle of the 80s, it was ported to various systems back in the days and in 1997 was ported to Saturn under the “Sega Ages” label.
The player ship, called Opa-Opa moves left and right while the stage loops; the object is to destroy all the bases in the level than face up the stage boss. Through each level a shop will appear and using coins released by killed enemies is possible to power up Opa-Opa weapons, but only temporarily.
This version obviously is arcade perfect and also includes the original soundtrack,a vocal song (along with a karaoke mode), and a replay mode with an expert playthrough.
It was released only in Japan.
