Ridiculously hard, but I did come back to it as an adult to finish it once. I think the minigames are fantastic, especially as they integrate in the story, since you need to win them to advance. Even with a second playthrough, it's a game that holds up pretty well, especially the easiest first half.

Not going to turn your world upside down by any means, also the graphics aren't great, but if you're in need of a decent GBA game, outside the classics, give it a try.
