Thank you very much for the feedback.
Yes you are right. Many points are not obvious, especially the need for sleep. The game does not have a full tutorial, so players may have difficulty understanding how to play and what to do.
Could you tell us more about the combat system? What exactly is wrong with it? We tried to make cards that can provide additional opportunities depending on how developed this or that skill is. I'm afraid it's not clear. For example, if you get a "book of protective charm" and you have a height parameter of strength, will appear the option to hit the opponent with the book.
