An escape book based on the escape room Wer Ist Wer. This project was born out of the necessity to let the people who couldn't experience Wer Ist Wer play the game at their home and with their friends. The challenge posed by this project was to fit an entire room inside a book, recreating and adapting physical puzzles and props in the two dimensions. A webapp was also developed as a way of checking solutions, getting hints and listening to the characters stories. Wer Ist Wer and Chi è Chi were selected in the 2021 ADI Design Index catalogue and for the Best Applied Game award in the 2021 Italian Video Game Awards.
