I like this game. I play it often. But the pay wall is real. For example: It would cost ~$35 to buy the best chest in the game. After hundreds of hours, you could earn it. Currently, not even halfway through all available content, getting this chest would not allow me to upgrade anything. I don't mind doing repetitive tasks for minimal rewards because I enjoy idle games. But it is worth recognizing that this game is unfair and designed to tempt you to spend money.
