If you're into old-school detective games, this Game Boy title based on Case Closed (or Detective Conan, depending on where you grew up) is a neat little mystery. You play as Conan, stuck on a suspiciously fancy train where, surprise surprise, people start dropping dead. The pixel art nails that '90s anime vibe, and the puzzles are just tricky enough to make you feel smart without needing a walkthrough.

First thing you'll notice? The dialogue is all in Japanese—no English patch that I've found—so unless you're fluent, expect some guesswork. But hey, that kind of adds to the charm if you're into retro imports. The train setting keeps things tight, so you're not wandering aimlessly like in some adventure games. Just watch out for that one passenger who definitely looks too innocent.

It's not the deepest mystery out there, but for a pocket-sized detective romp, it gets the job done.
