Guruguru Garakutas is one of those weird little Game Boy Color puzzlers that never left Japan—which is a shame, because it's got this oddly satisfying tile-flipping mechanic. You're basically rotating these circular panels to match up colored paths, and at first it seems simple... until the later stages start twisting your brain in knots.

The whole thing has this cheerful, almost toy-like aesthetic with chunky sprites and bright colors. I remember getting stuck on one puzzle near the middle where the solution was way more obvious than I was making it—took me like 20 minutes before I facepalmed and realized the answer was right there.

Definitely a hidden gem if you're into old-school logic games. Just don't expect an English translation unless you're playing a ROM hack.
