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.

I remember seeing Duck Amuck described in a Nintendo Power magazine back in the day, but I didn't remember and get to it until this year. Basically, it's a collection of minigames where you and Daffy are stuck in the white room from No Exit, and it's up to you to make his life miserable (well, any more miserable than it already is because it's Looney Tunes after all). It's a really cool proof of concept in many ways in that it utilizes many of the DS's features in both unlocking the minigames and throughout them, and most of the varied minigames hit the mark; some of my favorites here are the disc spinning minigame to make Daffy dance out of rhythm, and the piano minigame where you press incorrect notes when you see TNT rigged piano keys so Daffy gets pissed and "shows you how to do it." Not everything sticks the landing, but it's a pretty short and sweet collection with classic Looney Tunes slapstick humor. Would not recommend trying to 100% this, as quite a few of the minigames have to be unlocked through RNG idle conditions.

This was a minigames with nice animations kind of game.
I really like how experimental it was in many ways, like accesing minigames was a bunch of secret commands by itself, as the only screen aviable was just uuuh i don't know how this dude is called in english the duck the fucking fuck it was just him there and if you waited long enough a minigame appeared and if you did nothing something else and all of that.
Maybe you could count this as a precursor of The Stanley Parable and it wouldn't be too far from reality.
