I used to love this game, and I spent 10 dollars on the game from promotional deals and never felt guilty about it, because I really loved the game and thought it was worth the 10$ for all of the fun I got out of it. I also recommended several of my friends to play this game, and they purchased promotional deals as well. Now I'm very regretful for doing this, because it seems like this encouraged the devs to make this game more difficult once they realized people are willing to purchase the promotional deals. I now have hundreds of gems I refuse to use for a pay to win game. As long as the sponsor box is gone, I won't be playing.
