This game is pure pay to win, I would understand that and still play for fun if not for broken enhancement mechanics which are implemented in a way that forces you to pay if you want to climb a ladder. Enhancement i.e. gives you bonuses only if you are actually hiting max level cap. Buttons are put in a way that after accepting/drawing an item, you can basically dispose of it the same second as you accept. Nevertheless the game is much fun, and it's a shame they made it purely for income.
