Mickey's Adventure in Numberland is one of those weirdly charming NES edutainment games where Mickey Mouse runs around solving math problems. You jump on numbered platforms, collect items, and answer basic arithmetic questions—it's definitely aimed at kids, but there's something oddly satisfying about the way the levels are laid out.

The first few stages ease you in with simple counting, but before long, you're dealing with addition and subtraction while dodging obstacles. The controls are a little stiff (it is an NES game, after all), but the bright colors and cheerful music make it hard to stay annoyed for long.

If you're into retro Disney games or just want a nostalgia hit, it's a fun little time capsule. Just don't expect a deep platformer—this one's all about the math.
