With little advertising in the start screen I can live. More bothers me there already that you only get the Halloween Aquarium. But what totally anstinkt me: After a certain playing time, the game lets not start. Only when you about the app management deletes the data, it's back. Of course will begin on again from scratch. Have now played three times over 100 levels and each one fully equipped aquarium. Further, it does not go without the crashes.
