The level difficulty increases at a rampant rate, even linking FB and liking their page getting you 4k coins, isn't actually helping. The cost of leveling everything up is costly. The rate of difficulty isn't worth it. You get less than 200 coins per level, when leveling things up start at 400. And you need to have at least 3 new things to level up with each level. There's no way to actually get past level 40 without paying money to get coins, or gems. Do not recommend. Ugh. Money hungry app
