Great for little kids. Not so great for someone older than (I wanna say) 10. Played a demo of this game when I was little and wanted to play the full version. I'm 21 and was able to finish the game in 5 minutes.
I rented this game primarily for my youngest who just turned 5. He found the mini-games boring and repetitive and beat the game in less than an hour. That didn't bother him until he realized that the game doesn't change when you continue. Within 2 hours of receiving the game, he was ready to return it. I gave the game a "4" because the characters are very appealing and the concept of the game was intriguing for him.
