Play Castleween Online
You play as a kid lost in a haunted castle, solving puzzles while dodging jump-scare ghosts—it’s got that perfect creepy-but-cozy Halloween feel. The flickering candlelight graphics and timed puzzles keep things just tense enough without being scary.

Castleween is one of those GBA games that nails the Halloween vibe without being outright scary—just the right kind of unsettling. You're a kid stuck in a haunted castle, and the whole thing feels like someone turned a trick-or-treat mishap into an adventure. The ghosts aren’t too mean, but they’ll definitely make you jump when they pop out of nowhere.
At first, I wasn’t sure how to tackle the puzzles—some rooms lock you in until you figure out which key goes where, or how to distract that floating witch. But once it clicks, the whole castle starts to feel like a spooky playground. The art’s got this grainy, shadowy charm that makes everything look like it’s lit by flickering candles. And yeah, the clock’s always counting down, but it’s more fun than stressful—like you’re racing against your own curiosity.
If you’ve ever wanted a handheld Luigi’s Mansion with more keys and fewer vacuums, this is it. The music’s all eerie hums and sudden chimes, too. Perfect for playing under a blanket with a flashlight.
