Milon's Secret Castle

Milon's Secret Castle is a difficult and confusing action-adventure platformer for the NES where players control Milon, a young boy who must explore a sprawling castle to rescue Queen Eliza from a wicked warlord. Players use a bubble-shooting ability to defeat enemies and, more importantly, destroy hidden blocks that conceal secrets like money, health-restoring honeycombs, shops, and new exits. The game is known for its high difficulty, lack of clear instructions, and the need to find hidden items to progress.
