Super Wonder Boy - Monster World — About this game
A dragon and its monsters have conquered peaceful Wonderland. Bock takes up the challenge across twelve rounds, defeating enemies for gold and treasures and buying stronger equipment. Defeat a boss to obtain the key that opens the gate onward. Visit shops and taverns for supplies and clues, and look for hidden rooms rather than rushing straight ahead. The journey combines sword fighting, platform jumps and careful spending.
