Game: Choujikuu Yousai Macross - Scrambled Valkyrie (Japan)

Side scrolling shooter based on the Macross/Robotech saga. You can choose to play as Rick, Max or Miriya. Basically shoot anything other than you and collect power-ups to get additional weapon abilities. Most make sense although the fire shield type thing seems to more Science Ninja Team Gatchaman like instead of Macross.
