Summary: You could do way worse than this for a Wii title. It is very linear, which can be good or bad depending on what mood you're in. It struck me as a linear cross between Spyro and Psychonauts with some of its trippy level design. I didn't play the multi-player, but still found it to be a decent little title.
Summary: All of the downfalls of this game can be forgiven by the price. I bought it to play co-op with my girlfriend and it's fun for the most part. It works well with the wii remote/nunchuck. Some parts are very difficult for the non-gamer types. The fighting is very easy and simple, but some of the controls to get around are complex. There are parts where you need to swing from hooks, it took a while to get used to the play style for that.
Summary: I'm not a hard core gamer by any means...But I got the hang of this one pretty quickly. I love the look of the game and the music. My 5 year old plays it with me :). I have only gotten to Episode 3, but I can tell it will be fun!
