Ever heard of Ca Da? It's one of those obscure Game Boy titles from Japan that never made it overseas. The name doesn't give much away—turns out it's a puzzle game with this weirdly satisfying tile-matching mechanic. You're sliding blocks around, trying to clear the board before time runs out, and the music has that classic early 90s Game Boy charm (beeps and bloops included).

First time I booted it up, I had no idea what I was doing—the menus are all in Japanese, but after a couple rounds, you kinda figure it out through trial and error. Some of the later stages get surprisingly tricky, especially when the tiles start shifting on their own. Not gonna lie, it's one of those games that feels simple at first but hooks you once you get the hang of it.

If you're into retro puzzle games, this one's a neat little hidden gem. Just don't expect a tutorial.
