I like the concept of merging item, i'm at Stage 17 and the game slow down a bit compared to the first ones due to the boss one-shoting more than half of my heroes but i enjoy this. Hope there will be update (bigger inventory, merge all button etc).
When I began this game, I was level 1 searching to spend my time, I loved this game at the first second. Now I'm level 900+ and i still love this Amazing game ♥
