Play Milon's Secret Castle (USA, Europe) Online
You bounce bubbles at enemies while tapping every suspicious wall, hunting for hidden rooms in this quirky little castle crawl. The cheerful music almost makes up for all the times you’ll get stuck.

Milon's Secret Castle came out for the Game Boy in 1986, developed by Hudson Soft. It was one of those early portable adventures that felt ambitious for the hardware, a full action puzzle game you could carry in your pocket. The screen was small, the colors were shades of gray, but it offered a big castle to get lost in.
You control Milon, a young boy with a bubble shooter, exploring the castle room by room. Your goal is to rescue a fairy queen hidden somewhere inside. You shoot bubbles to defeat enemies and reveal hidden doors by bombing specific walls; much of the game involves methodically checking every surface for secrets. It moves slowly, demands careful observation, and can be brutally unforgiving if you miss a key item. Playing it feels like a deliberate, sometimes frustrating treasure hunt where every new discovery comes from your own stubborn curiosity.
