This is Mimpi. See Mimpi run. Run, Mimpi, run! Avoid that rotten tooth that could crush you to death! Fetch the bone, Mimpi! Don't touch the starfish!
Admittedly, the most noteworthy thing about Mimpi is the colorful, almost PixelJunk-esque art style, though some of the mechanics shown look neat in their own right. It looks like it moves a bit slowly and control of the dog itself is likely limited due to the touch interface, but that doesn't really matter right now because Mimpi is super cute and I just want to snuggle it to sleep.
