I played this game quite a bit about a year ago or so and got to level 121. I decided to come back and play again and now I legit can't beat level 20 anymore. My armor was in the 10s of thousands and it is now double digit and everything one shots me. I have about 6000 diamonds but nothing in the store is anywhere remotely close to bridging the gap. I have 2 questions. Was there an update at some point that rendered this game unplayable, and is my file salvageable without dropping thousands of dollars?
