Good thing the app was free today. I would pay anything for it. If you have to kill than 5 minutes time it is ok, but a Langeitspielspaß does not exist. It quickly becomes confused and monotonous, eventually you run out of points for repairing and all upgrades are purchased. Have the app uninstalled. If I have five minutes of boredom, I prefer looking through the window to the outside; ^)
