Milon's Secret Castle — About this game
Milon explores a castle to rescue Queen Eliza, using bubbles to uncover routes as well as defeat enemies. Hidden coins, shops and tools are essential to progress: shoot suspicious blocks, find each maze room’s key and buy items that overcome particular obstacles. Boss victories yield crystal balls that open the next stage. Music boxes lead to note-collecting bonuses, and passwords begin after the ground-floor boss, helping preserve the search through the castle. Begin in the castle’s ground-floor rooms.
