Brain Drain on Game Boy is one of those puzzle games that looks simple at first—until you realize it’s quietly frying your brain. You start off matching shapes or sliding blocks, thinking, "Okay, this is chill," but by level 5, you’re staring at the screen like you’ve forgotten how to think. The puzzles escalate fast, but in a way that makes you want to solve just one more before putting it down.

What I love is how it nails that old-school Game Boy vibe—no frills, just pure puzzle logic with a side of pixel charm. Some levels feel impossible until you spot that one sneaky move, and then it clicks. (And yeah, I definitely got stuck on the ice block stages longer than I’d like to admit.) If you’ve got a soft spot for handheld classics that actually make you work for it, this one’s a no-brainer.
