From installing the audio files to play through the present day has not everything works perfectly, except for one little problem: on one day is the game just repeatedly asked the same question. A small criticism even at the Christmas Market game: associate the sounds heard correctly, was sometimes so difficult that even I had to look far. My son is very patient, but some other children were there probably quickly get tired.
In addition, the perforation could be made of the door so that they are somewhat easier to open. Younger children need help with this if you are not accidentally tear the whole calendar.
But otherwise really a top product! I would love to buy again next such calendar for my child. Therefore, it would be great if Ravensburger might still considered a few more Advent variants, because again, the same would of course no longer as exciting. I think there are plenty of other issues on which we could develop a calendar, as to experience "just" the holiday season with your family Tannheimer.
