Not... very good. It's respectably ambitious for what it is, trying to capture both Super Mario Kart and Mario Kart 64 on handheld. Controls are so slippery - don't think I've ever leaned so much on hopping and breaking just to make a normal turn, on top of only being able to win as a heavyweight when I usually play as lightweights. The game is arbitrarily mean about high-end completion, down to punishing players for picking better characters.

For a casual playthrough, though, it's fine enough. There's better mobile options for Mario Kart now, but in 2001, it'd do
