About Castleween
Castleween came out for the Game Boy Advance in 2002, developed by Neko Entertainment. It was part of that wave of spooky themed platformers that felt right at home on the handheld, sitting alongside other adventure titles without much fanfare. You don't hear about it often, but it has its own quiet spot from that era.
You control a boy named Mike, exploring a haunted mansion room by room. Your goal is to find your lost friends and escape before midnight. The gameplay involves navigating screen by screen, using a sword to fend off monsters and a vacuum to suck up ghosts. You collect keys to unlock new areas and search for special items that reveal hidden passages. The pace is deliberate, with some tricky enemy placements that make you plan your moves. It feels like a careful, methodical crawl through a creaky old house.
