Double-panel LCD game (there are two LCD panels on top of each other). The dual panel creates a kind of 3D afffect with lower objects on one panel, and higher ones on the other. Released in Japan, it's known as Amazone (or is that Amazon E?) in the U. S. and other parts of the world. Neat design, I know of these Double-panel games: Airport Panic, Frankenstein (or Mr. Franken), Hikyo Amazon (or Amazone), Terror House (or Akuryo no Yakata), Zaxxon. All but Zaxxon are solar powered games.
