A really fun game horribly overshadowed by the lag issues. While the game-play is good an fun, like a very improved Temple Run. The big problem is it's difficult to progress due to lag which causes control difficulty and often complete game crashes. The lag also blocks achievements form being unlocked even when they are shown completed in game. There are also many micro transactions which are typical in mobile games however this game allows you to earn these items in game at a decent rate and progress in the game without them at all which I attribute a point in it's favour.
It's hard to review the game in it's current state but if I could play it without lag and crashes I'd give it a 5 for a mobile game!
