Cool Ball is one of those Game Boy games that looks simple at first—just a little ball rolling around—but then suddenly you're sweating over pixel-perfect jumps and dodging enemies like it's life or death. The controls are tight, and the levels get brutal fast, but in that satisfying way where you know you can beat it if you just try one more time.

It nails that classic Game Boy vibe: chunky sprites, bleepy music, and that weirdly addictive loop of "okay, just one more level." I lost way too much time to this as a kid, and honestly? It still holds up. If you've got a soft spot for retro platformers that don't hold your hand, this one's a solid pick.

Just don't blame me when you're muttering at the screen after the tenth failed attempt on level 5.
