All die schönen Spiele oder Entdeckungen in den unterschiedlichen Räumen, die im damaligen und gleichnamigen Spiel möglich waren, fehlen leider! Keine Kaufempfehlung! **Developer response:** Hi, I’m guessing you’re referring to the old cd rom game from the 90s. When making a modern app version of the book, we wanted to present the books feeling and atmosphere to young children in a more sober way. We hope your children can enjoy the app. ## Frequently asked questions about Knock, knock, knock! ### What is Knock, knock, knock! about?
