Pop Up (or Cool Ball, depending on where you got it) is one of those weird little Game Boy puzzle games that somehow sticks with you. You’ve got this grid of colored balls, and the goal is to clear them by matching colors—simple, right? Except the twist is that you’re popping them in a specific order, and if you mess up, the whole thing cascades into chaos.

At first, it feels like a stripped-down Tetris clone, but after a few rounds, you start seeing patterns. The music’s got that classic Game Boy bleep-bloop charm, and the controls are just responsive enough to make you blame yourself when you screw up. It’s not flashy, but it’s weirdly satisfying when you pull off a big combo.

Definitely one of those "just one more try" games.
