Initially, it was great! Game was fun and the ads were simply an optional pick if you want to clear a stage or level up faster. But after the ui changed, this game has gotten wayyyy too comfy with the ads, not only that, drop rates for clones is now low along with a buggy forge system. They removed rewards for clearing stages and replaced purple keys with soul stones or scrolls. Not only that, it took some of my gems for absolutely no reason too! Lost around 600 gems after playing clones!
