I originally bought this for my nephews to give them something to play as Demons Souls, Mortal Kombat and Dynasty Warriors weren't appropriate for their ages. They think this game is great, it's got just the right amount of challenges for young and older gamers.
As a result I've got hooked into this game too, it's got trophy support, co-op mode and is a lot of fun. The music is excellent, it gets more musical as you color things in and complete tasks and the each level is quite long too which adds to the fun.
My only criticism is that there's a timer for the levels which seems not needed. Occasionally i'll get stung and run out of time but usually you can get the timer to be over an hour remaining by completing tasks.
Great for kids, great for adults and great to not be inflicting death and pain in order to win for once :)
