Well done and immersive, many possibilities with a lot of characters!
The only problem are the iAP, way to many of them. You should reduce the cost of the characters and reduce a lot the cost of real money for the orbs.
Other than that, good game and cool time waster. I want to encourage the devs, but I would have preferred to pay 4-5$ for this game instead of all the iAP inside it.
