Engaging game but it is the biggest Whale hunter I have seen. Imagine this: A good hero is sponsored in the shop. You have a guarantee to get it within 180 hero purchases. Problem is, each single purchase is equivalent to $5. That is $900. But 1 isn't enough, you need multiples of the same hero to unlock their full potential. The game has no "sweep" function and will take HOURS of your phone battery to waste your energy (which you do get plenty of thankfully) The story is.... Meh.
