Migrain (Japan) is one of those weird little Game Boy puzzle games that somehow sticks with you. At first glance, it's just another block-matching thing—but then the headaches start (fitting, given the name). You're sliding tiles around to clear paths, but the rules aren't obvious right away. I remember getting stuck on the third puzzle for way too long before realizing I'd been overcomplicating it.

The Japanese version has this oddly charming, slightly creepy vibe with its minimalist graphics and those sharp little sound effects. It's the kind of game you pick up thinking "eh, five minutes," and suddenly you're muttering at the screen because the solution was right there the whole time. Not for everyone, but if you like puzzles that make you feel dumb before the "aha" moment hits, it's weirdly satisfying.
