Some mini games are near impossible and decrease the fun and increase the frustration level to want to not even want to play. Also, the reward chests. I have to do a task or something to earn the chest AND THEN HAVE TO PAY to open it. And why are some chests 3 bucks and others 5? Keep them all free. We did have to complete a task of some kind to earn the chest after all. If we have to keep paying to progress in the game people are going to quit all together and you will have no players.
