It's really good, if and only if you pay to remove the ads. Like: did you farm a lot of materials to unlock a piece of land? Here's an ad to celebrate it. Did you spend all the hard earned materials to upgrade your pickaxe? Here's an ad to comemorate this moment. Plus the ad banner, ad watching for materials, it's a lot, too much. I still rate it 5 stars because it's fun, and I am waiting for the next update, but please tone down the ads.
