Could be a great idle game. However, after chapter 1 &2. It's starts to get difficult very quickly. After upgrading characters you notice they are very spongy against even low level mobs. Very unbalanced game play especially in pvp. The pay wall creeps up on you as well. You will grind quite a bit. However, it helps they have a sweep selection which doesn't need sweep tickets. Hopefully they'll make positive changes in the future.
