I hate everything about this game even though I still play it. With a network level ad blocker, you don't see any ads but that means I can only play at home. None of the upgrades you buy with gold seem to do anything. The "leaderboard" also means nothing. There are some levels that are just impossible to beat. Eventually if you do well enough they just start giving the "rivals" shields so you get the minimum reward. This game is designed to prey on people with ADHD.
