Alex Kidd: The Lost Stars (set 1, FD1089A 317-0021) — About this game
Alex Kidd: The Lost Stars (set 1, FD1089A 317-0021) sends Alex and Stella through a sequence of timed platform worlds in search of the lost zodiac treasures. Toys, machines, underwater scenery and a giant body turn the next route into a different obstacle course, with miracle balls hidden in unlikely containers at the destinations. The arcade journey uses a limited life supply as well as the timer, so a successful jump needs a safe landing rather than merely a forward direction. Learn the first obstacle’s spacing before pursuing another treasure, then keep enough time to finish the current world.
