Not much different than other puzzle apps
Update 19 Dec 2014: I was updating all my apps and noticed this one, and that the update notes said, "Cross-promotion bug fixes." Its outrageous that I have to use 176MB of my monthly data limit for this reason. Funny, I didnt even remember rating this one six months ago. Now Im downgrading my rating to 2 stars.
I was taken by the rave reviews, but really, this app is not much different from other puzzle apps available here. Sure, once the puzzle is complete the item can be made to move or make a noise, but its low-level entertainment. Maybe its great for under-threes, but my nearly four-year-old played with them once, and hes kind of done. Not worth the money for just one afternoons entertainment, compared to what else is available. I do like that there is no in-app purchase, though.
