I have reached level 72 . I won that level and tried to go to next level. I was told I needed 1 more star. I returned to the current level and have won 2 times since I received the notice the first time. Each time I tried to move up to next level and I was told I need another star. Well when I won initially on level 72 I received 2 stars. Please advise . I understand it is your job to make money but I am getting a little irritated. I have made it this far without any purchases and I will keep it that way. Are purchases required to move up!. I noticed that the game took a turn for the worst after I gave you a great review. I almost want to take back my positive review. Thank you.
