The core game it self is ok, once you get to the 4th check point of the game it gets really hard to progress. You drain your stamina so fast and you regain it really slowly to where you can play the game for about 5 minutes and your done. The hero progression is absurd and makes no sense to me. Why can't we just get the item we need to level our heros. The summoning is the biggest scam I have ever seen. The rewards for clearing hard level are extremely low. Not worth playing.
