I beat the game when I was... 8! I got all the characters (except that doctor guy, because the game broke before I was able to get him) I got Gon, though. THE BEST GAME EVER!
I can vaguely remember this game. All i can see in this game in my head is running away from a huge boulder, frossing a weak bridge in the fog, and being on a beach with crabs going from side to side.
