You can reach over 100 levels even without spending money

It's not that easy to clear, and there are times when I get stuck on the same level for three or four days. You need to participate in many events to get some items and level up to slowly beat it. Overall, it's a great game with diverse gameplay and enough stamina to play. I've personally tested it and reached level 110 without spending any money! The ad-free weekly pass is $30, and after buying it eight times, it's permanently activated, which isn't too expensive. However, there aren't that many ads to begin with, and you can slowly watch them while doing other things to get rewards. But if you want to change skills in-game, purchasing it would be quite convenient.
