Update- having read some of the other reviews (I'm doing this game as a cash-pay app game) I have to take away a star. Didn't realize how much they messed things up. I give this three stars for the following reasons: The good- the game is interesting. I like the concept, and despite the below, it is somewhat fun. Your mission is to build despite the limits. I find that somewhat intriguing. The bad- it is utterly frustrating to hit multiple limits. All over the place. Storage limits, limits on how you can build. It can get frustrating. But workable, it hasn't stopped me, and I just wait longer. Though the addition recently of watching ads to speed up some processes has helped a lot. The ugly- the ads are helpful to get things done. I get that. But I don't like the ones that have a 4 pixel close spot, and all other taps bring you to Google Play store, or a web site. I mean, I just sat through the ad. Don't frustrate players with yet another, non-winnable game. That's cruel. (it may be more about the ad agency the game contracts with, but I can't leave THEM a review, so here we are.)
