From what I remember, (can't be bothered to look it up) it was released after the GBA came out, so not a lot of people bought it, it's a licensed game, (more often than not a death knell for any game), so not a lot of people bought it, it's a kid's puzzle game and can probably be beaten in an afternoon, again not a lot of people bought it
As far as I'm aware it's "uncommon" rather than "LEET RAREZ!!!"
Gameplay wise think "vvvvvv"
