The first three levels are great. Nostalgia and the novelty of playing around with the proton pack makes it enjoyable. But the game is pretty repetitive and the dialouge/jokes (although great at first) get cheesy towards the end. Get it cheap and have a couple of hours of fun.

Really neat art style, original characters and fun game mechanics. If you liked Shadow Complex, Trine, or Klonoa and other side-scrolling 3D platformers you'll like this!

Over 100 hours spent on the Xbox 360 version. One of the most enjoyable role-playing games I've ever mucked around with. It lets you play however you want :)
