Normally I would give a game this good a higher rating despite its problems, but in this case everything fun about it was borrowed from other games, while the few additions only serve to annoy.
On top if that, the game forces video ads every two levels, and offers no way to buy out of them. Thus far nearly all of these I've seen were for violent games, one of which was so bloody I'm a little surprised its on the App Store. Nothing an adult gamer can't look past, but makes this otherwise harmless puzzler unsuitable for kids.
