When I first started playing the game was fun!!! It was so fun I was spending money! Then I noticed I was having to spend to much money every few levels once gems ran out. They don't give you enough time to complete the level and if you want to complete level you have to spend 35 gems for 30 extra sec then 50 after that! It should be like 10 gems! Each level you only get like 200 coins and upgrades can be 1,000. Please fix. I would love to cont playing. Not for so much money though!!
