I would give it 1 star but the game play is good enough for a star. game does not really explain all the ways to get characters. Summoning them is one way Most games like this you can save up shards and combine them to summon. Here is my issue. They have a deal going on in the shop. I spent 60k Visiore "gems or diamonds" and bought 40 shards of a lot of characters. Found out I wasted my Visiore. 6k is $100. I saved mine but you can see the problem. To get them to use you have to pay real money.
