Sky Shark

Sky Shark is a top-down shooter similar to Raiden. You start off with four
lives and three bombs. With that (you can get more lives at certain point
intervals, and more bombs can be found), you, the “Sky Shark” of your
squadron, blast through five levels of enemy-infested battlefields with as
many as six gun upgrades (Aside from the bombs and the gun upgrade, there are
no other weapons to be found at all). Includes three difficulty levels and
two-player support.
