You play the role of a sailor who has been shipwrecked on an island in the sea. A girl passenger was with you but is no where to be seen. Using only the items you discover as you make your way around the island, solve the puzzles and the mystery of what lies before you. Can you find the girl and escape?
Apparently this isn't the first time these two kids have been in trouble. Phantasy Quest is the first adventure game based on a series of Flash animations spanning back to 2002, which were inspired by a 1981 video game called Fantasy by Rock-ola.
