Zunou Senkan Galg

Zunō Senkan Galg (頭脳戦艦ガル), is a shooter developed by dB Soft, who bills it as a "Scroll RPG" on the box. This is supposedly intended to imply that there are RPG elements involved in this vertically-scrolling shooter, but the reality is that there are very few RPG elements. The only two obvious ones is the need to find parts for your ship, and the fact that you can choose which path to travel along.
