My personal favorite mobile game. I've just recently caught up with the updates. I've been playing this game on and off since 2015. The worst part about the game is one word, Treasures. They are completely required to advance through anything past the second chapter and require tons of grinding. Once you have all of the Empire of Cats treasures, the game just keeps getting better and better. There is some treasure grinding, but not as much. The strategies required to beat some stages are so intricate and cool. The gameplay gets extremely deep, despite the cute and simple exterior. The game is continuing to be updated and the updates are getting better, as shown by 10.9, the update with aku enemies. When it comes to microtransactions, all of them are such bad deals, that you will never be tempted to spend a cent. I love the game, and if you can break through the boring grind of the early game, you can have a great time.
