Play Castle Excellent (Japan) Online
You're Prince Rafael sprinting through a maze of locked doors and gremlins, where one wrong turn means retracing half the castle—those keys disappear fast. That old NES tension where every beep and pixel feels like life or death.

Castle Excellent (or Castlequest, depending on where you played it) is one of those old-school NES games that looks simple but gets weirdly tense. You play as Prince Rafael, who’s basically just running through this massive, maze-like castle trying to rescue the princess—classic setup, right? But here’s the thing: the castle’s full of doors that lock behind you, keys that vanish if you take too long, and these little gremlin guys that pop out of nowhere. Mess up once, and suddenly you’re backtracking through half the map.
It’s got that early NES charm—chunky sprites, beepy music, and the kind of trial-and-error gameplay that makes you mutter “oh come on” at the screen. The MSX version’s a bit different, but either way, it’s a neat little relic from when platformers were still figuring themselves out. Just don’t expect any mercy if you forget where you left the silver key.
