Pretty impressed with this game which really makes great use of the move controller. It's a fun game with quirky graphics and upbeat (if slightly annoying) commentary. The demo (downloadable and playable if you already have a controller) gives some idea of the game, however doesn't show some of the best of the 20 mini-games. We particularly enjoy popping the blow up fish, zapping robots and also slicing falling fruit. Some of the games are a little bizarre - one involves you using the controller as a fan to blow chicks to safety, but in the main they are well thought through, bashing a donkey pinata and brusher a crocodile's teeth is great fun. This is, as others have said MUCH better than anything you can get with the wii - mainly as you are playing in effect in 3D - when you have to paint on the screen you really feel you are doing it.
This is a fun game for kids - the controller is quite big for small hands, my 4 year old can manage - just - it's ideal I would say for age 7's and above and to play as a family. There are lots of fun elements and challenges, and you can make your own avatar and voice recording via the eye camera.
Overall, great fun, and likely to be fairly long-lived, though it does get a bit samey after a while, kids seem to love it!
