There's (of course) too many ads. In the second level ALONE 4 ads played, almost everytime I filled a container. It also didn't let me put the items in spaces that clearly had enough room, so I had to take the surrounding items out before placing. Over all, the idea and actually gameplay is good, but just like majority of the play store's popular games, is over run by ads. At this point it's just an "ad epidemic."
