Passing levels r too hard and gotton 2 the point where its downright LUDICROUS.this game will literally sabatoge you and on top of that you can barely win enough coins to even upgrade making passing a level painfully slow+if you can't upgrade, you can't advance unless you drop alot of money(don't do it. U won't benefit)+ when you move on to a new world you loose all the coins and have to start over with different coins to upgrade and move on again. Ew, No thanks!Dont waste your time.Uninstalling
