Action maze-game based on the legendary "Binary Land" from NES about moon and sun.
You control not one, but two characters at the same time. While you are in direct control of one moon, you indirectly control the sun, which moves in mirror image fashion from the moon. When you move your moon left, the sun moves right, and vice versa. The goal of the game is to move both characters from the bottom of the screen to either side of the caged heart at the top. There aren't too many enemies to worry about, mostly thunders and their webs, and they are easily dispatched with the magic-dust gun that both characters fire simultaneously.
