Good, fun game. My problem are the ads. Ads when you level your gear, ads when you unlock a new world tile, ads to get resources, and if you sit idle for 30 seconds, it gives you ads. Sometimes, it will give you not one, not two, but three ads in a row and it won't give the reward unless you watch every ad it throws at you. And it throws ads like a blizzard throws snowflakes. Fun and relaxing game, though!
