It's an OK game. The gameplay is good, and so is the interface/graphics/sound. However, it seems like there should be a story that's missing--not that it needs one, but that there was space left for it and they decided to skip it, so the "extras" in the game make no sense. The BIG problem is the ads. Pls rethink your ad placement. When i lose a puzzle, forcing an ad after every time just makes me close the game. I'd be tempted to watch ads for bonuses if I didn't constantly already watch them.
