the game is improved the last time i played because they added exp. and you can do it faster. they haven't fixed the invisble glitch. mostly everthing is money the cave is not worth it and all of them but on volcano island you have advanced miscrits. I like that they let you in about around when you beat the life boss. everthing is lame is not fun a lot. go if you have a facebook acount its much better because they have the cave cheaper but you spend money. i think. i think the water,nature,and earth is much easrier.
