Here's the description:
A powerful storm propels your prototype air craft many miles into the sky! Above the clouds you land in a strange, undiscovered land in the sky, full of sky palaces, strange creatures, and many dangers. Collect Golden Crowns, Ancient Weapons, and Precious Gems. Find power-ups to assist you and escape from the mysterious Air World!
