it's ready now at both languages (I hope so)

Perhaps you should take your kata back to draft for the time being while working on it.

Thank you for the feedback. You are right about being more straightforward. That was because the kata got a lot of development here in the beta process. In the beginning, the main idea was a children's puzzle: what minimum part of the book should lie on the table so that it doesn't fall down (try to answer;). Madjosz did a great job, and now I need time to consider everything.

Thanks, Concker88.
Nice job. It looks right.
