In short, this is a brilliant game with beautiful artwork, endearing characters, and challenging puzzles. My girlfriend and I played it together while travelling and we got lost in it. The puzzles are just the right level of difficulty without being impossible for too obscure, and the story is told brilliantly without dialogue.
I played this briefly after having played titles such as X-Wing, TIE Fighter, XvT, X-wing Alliance, etc. Basically it's okay if you're five and don't have the coordination or gaming skills to play any of the previous titles, but it lacks any sort of difficulty or satisfaction that the brought, as well as challenge for the intermediate and above gamer. I wouldn't waste your $5.99, it could be much better spent.
