Horrible UI design, difficult to find information, and an extreme amount of microtractions that is completely pay to win. You constantly get bombarded by ads for spending more money. Response to dev reply: It's not difficult to make it fair between those parties, there are tons of games that do microtransactions correctly. You are just greedy. And UI design is not difficult if you have years of time and feedback to perfect it. I would know as I program and design for a living.
