In my opinion the ads are intrusive which caused me to buy the ad removal pack (which included in game items as well) for $10 (USD NOT including tax). Overall it's a good game to pass time. EDIT: Turns out the ad removal pack isn't entirely worth the price granted SOME of the in game items help with your progress but overall it's worth it as a one time IAP. I do wish it was easier to get certain resources without having to "grind" or make multiple IAPs.

Strong potential, but you're playing while they build content and fix design bugs. Some hit boxes are inaccurate (huge flaw for a game about hitting). Advancement requirements are not always clear, and often change. Upgrading/merging gear is a hot mess. Trader loot is restricted just to slow you down. Many required quests have no payoff. Arbitrary "CP" level requirements mean you're OP by the time you're allowed in (therefore, no real challenge). Might be worth pay-to-play at some point.

I tried to play it for 2 days. I had constant ads, lagging, and it literally spent several minutes loading every time I clicked on a task. I also had trouble with loading other apps as well. Once I gave up and uninstalled it, my phone started working fine again. I'm sure there's something wrong with the app itself... maybe even malware.
