confused purchasing system

The first maps have to play quite well. However, one is bothered already here already with the tangled Inn-app purchase system. There are hearts, game dollars and stars, and of course genuine Euros for which you can buy that somehow verkettenen points and dollars star heart. The Quick Maps are then raised in difficulty, that you can not do without additional, and very expensive purchases. Among other things, an in-app purchase packages of just 50 euros must be offered as a special offer simply usury and an impertinence. I uninstall it again, also it is an extreme memory hogs with just 200MB.
