Spiral campaigns.

Campaign 1. I finished it yesterday. It contains 4 maps. They are arranged in the campaign as follows: maps 1, 2, 3 are played, then maps 1, 2, 3 are played again, but with a stronger hero, and finally map 4. At the beginning, you get a hero. Then you level him up to level 3 on each map. What I would like to modify. At the beginning, I want to give the hero with skills not 0-0-0-0, but 0-0-5-5. Also, the maps should be longer, but that will take time. In the next campaign, I want to remove the two shortest maps and add two longer maps. The archive contains a ready-made campaign with 7 maps, as well as 4 map templates for it.
