I've started playing this game on mobile since the very beginning, when there were only knight,ranger and witch available. Got all the class decks. I love it. I will not pay again for the classes I have on my mobile account cuz why would I do that? I am currently trying to beat horror on every class and as the game progresses, sometimes it feels unfair. But it is always fun to try and build your deck to survive your enemies.
My only issue is that the nun class final boss on hard levels is not fun since it counters a lot of classes. I can't beat it with magician for example. But we live and we learn.
