Ginga Fukei Densetsu: Sapphire

In the future, time travel became a regular commodity. Criminal organizations began using advanced science in order to escape into different time periods to avoid capture. To counter that, a special police unit called "Burning Rabbits" was formed to fight through time and space. Ginga Fukei Densetsu: Sapphire is a vertically-scrolling shoot-em-up. The player can choose between four different female characters, each piloting a different ship: Sapphire has balanced strength is speed; Charlotte is the fastest, but also the weakest; Helen is the slowest and the strongest; Jasmine is the second-strongest and the second-slowest. The ships are also distinguished by their weapon properties. Each ship can collect red, green, or blue power-ups; collecting a power-up of the same color enhances the currently equipped weapon, while a differently-colored power-up changes weapon properties while retaining whatever enhancements the ship might have had with the previous weapon.
