It's alright, nothing crazy. The levels are pretty linear with occasional nook and cranny. The level design is alright, and the combat is fairly repetitive, there's not much enemy variety. There are frustrating aspects, like sections where you have to throw an objects at something and these are pretty slow and boring, and if you fail, you'll have to repeat them again, although there aren't many instances of this. The collecathon aspect is actually kinda lame. There's loads of coins that are only required for the last level to beat the game, aside from that there are stars, the only collectibles that are actually useful, as they augment abilities for every 50, like adding a glide ability to the jump, or making midair tail attack more powerful or allowing to roll indefinitely. Lastly, there are crystals that unlock worhtless mini-games, like button mashing for beavers to drop a tree, or button mashing for a race. There's not much to say really, it's a fine enough 3D platformer if you're starving for those, but if you want a great 3D platformer experience, play something else, like Super Mario 64, or Ratatouille for the Wii.
