Guru Logic Champ is one of those weird little GBA puzzle games that never made it outside Japan, which is a shame because it's got this perfect mix of simple mechanics and brain-melting challenges. You're basically sliding blocks around to guide a little dude to the exit, but the twist is you can only push—not pull—so every move counts. Mess up once and you might have to restart the whole puzzle.

The art style is super clean, almost minimalist, with these bright colors that make it easy to see what's going on even on the tiny GBA screen. The first few levels trick you into thinking it's easy, then suddenly you're staring at the screen for 10 minutes trying to figure out how to untangle some nightmare layout. There's no English translation, but honestly? You don't need it—the puzzles speak for themselves.

If you're into stuff like Sokoban but want something with a bit more personality, this is a hidden gem worth tracking down.
