Milon's Secret Castle (1986). Play online

Summary

In Milon’s Secret Castle I guide Milon through Garland Castle, running, jumping, and firing bubbles that double as weapons and tools. A bubble can shatter a soft block, revealing hidden shops, extra routes, keys, or power‑ups, while the same shot also pops the resident demons—though they re‑materialize after a few seconds. Each room has a single fixed exit, but the layout lets me explore rooms in any order. The castle’s walls blend soft and hard blocks indistinguishably, so careful bubble‑shooting is essential to uncover every secret.
The challenge is brutal: you get just one life, and death means a complete restart unless you’ve captured a crystal ball, which grants a one‑time continue. Every room also features a honeycomb that fully restores Milon’s health and even expands the life meter. Because Milon never "blinks" to become invincible, I have to stay constantly on the move or risk quick depletion. Lightning strikes the castle if I linger outside too long, adding urgency.
Originally dropped on the NES in September 1988, the game later resurfaced in Hudson’s Best Collection Vol. 3 for the Game Boy Advance and on several Virtual Console services, keeping its quirky difficulty alive for new players.

Storyline

The game follows Milon, a tone‑deaf boy from Hudson Land, where residents speak through music. Before his journey he visits Queen Eliza at Castle Garland.

Upon arrival the castle is overrun by the evil wizard Maharito and his demonic army, who have seized the people’s musical instruments. Determined, Milon enters the fortress to rescue the queen and retrieve the stolen instruments.

The adventure pits him against seven bosses. The final foe is Maharito himself; the other six are Demon Beasts named Homa, Doma, Blue Doma, Red Homa, Red Balkarma, and Kama. Defeating each yields a crystal that upgrades Milon’s power.
