I remember reading about this in Nintendo Power as a kid and it never left me. The concept is really cool, animation and voice are on point and very high quality for a Nintendo DS title, but man playing the game it's just not there.

The minigames range from incredibly simple browser games to tech demos (which is silly as the console's been out for 3 years at this point), and you don't get any instructions on the minigames beyond knowing that you're supposed to do either what Daffy doesn't want or what will lead him to getting the most injury. It does use everything the DS has to offer, and I especially love the minigame where you close the DS and have to press L and R with Daffy's directions. The voice work is strong here and that also helps. On the other hand you can feel the budget in spots, like the Brain Age parody is just a still image of Bugs rather than a proper 3D model like Brain Age, and lack of voice acting for Bugs there as well.

Provided you can find enough minigames to play (as you can only find them by fucking around with your touch screen or console in various ways) the game will end in about an hour, providing an in-universe explanation for how it came out the way it did.
