Nice interface. Way too many ads. Many are unskippable. I had well over a hundred my first and only day i had the app. Im likely underestimating as i needed at least 6vfor evry level of item and I leveled up 3 items to level 7. Never mind the ads needed for raw materials to open up nearly every hex on the map. Lets split tye difference 200 ads for 4 hours of play. Nope.
