This is a great game for all ages. First things first, I didn't know how I felt about the no jump option, but after you get the feel of the game, look out...it is amazing.
The sound is incredible. The music written for all stages is tremendous, probably one of the best soundtracks I've heard for a game in a while.
Graphics are great as well. Each world is perfectly detailed and is fully interactive. It's nice to have a game that looks so good, and plays just as well at the same time.
Some parts of the game I found to be troubling, and didn't really make sense, but I guess that is the way some games are. But overall I feel this game is a deffinate purchase for any GameCube owner. Tons of Fun!!!
