Therefore, I plan to make a free addition to the game created by my father, with the Overlord’s Health (OH) disabled. That is, when playing Father vs. not-Father, OH will not be active. But I will also see how the second week of the paid version goes...

I welcome this decision!

There is also a suggestion (I don't know how feasible it is). To somehow distinguish players from the HW resource (those with a rating). The problem is that quite a few "beggars" from GameRanger, etc., have signed up, and many not only don't know the HW rules but also refuse to learn them. You come across jerks, and the game with them ends either with them leaving, or with rudeness and insults... (HW players, for the most part, are much more disciplined, with rare exceptions).
I understand that this is not easy, as many have different nicknames in the lobby, different from their HW nickname. For example, mine simply didn't fit in the lobby due to the number of characters during registration.
