Ever heard of Tsuukin Hitofude? It's this weird little GBA game from Japan that feels like someone mashed up a rhythm game with a minimalist art project. You're basically drawing single, continuous lines to the beat—sounds simple, but the timing gets surprisingly tricky.

First time I played, I thought it'd be a snooze, but the way the music syncs with your strokes is oddly satisfying. Mess up, and your line snaps like a rubber band. The whole thing has this clean, almost hypnotic vibe—definitely not your typical GBA fare. If you're into niche Japanese rhythm games, this one's a neat little time capsule.
