This is an unreleased Genesis title that was unreleased for a reason. The difficulty curve is insane, especially for the scrolling shooter genre. The trial and error is ridiculous as you often have no chance of surviving unless you replay an area at least a few times. THE GAME EVEN HAS A TIMER ON TOP OF EVERYTHING! This is all brought to an epicenter of fail with the fact that the lives are limited and your patience is not. A solid 3 out of 10 is giving the game too much credit, but, it deserves something for responsive controls, an interesting story concept, and fairly good graphics.
