Not great. It controls well, and the platforming is satisfying. That's all there is too this game. Level design is basic and boring, bosses aren't fun (a cardinal Mega Man sin) and there's enough trial and error to pad out a short Gameboy game.
Really has aged poorly. Nothing too awful about it, but it's just a mediocre racer now with some control and ai issues. Can still be plenty fun, but shows its flaws.
