This was fun when it first came out, but the uniqueness had faded. Heavily reliant on microtransactions to boost gameplay, and it's almost impossible to get past certain levels without boosts, which are scarcely given and very easy to blow through. Even the side games, which were a good way to pass the time until your lives restored, are behind paywalls after a certain point. Additionally, there is no way to back up your account other than through FaceBook. A gem of a game gone tarnished.
