I played the initial version on a hero and completed it in 152 days (I received an Archdevil). I leveled up light, darkness, defense, luck, and logistics with all the perks. I didn't befriend the elves; I just defeated them, and I didn't regret it because I got a lot of artifacts and useful spells. I didn't have any major problems with the blue "kamikazes" and the red ones. However, the "earthquake" I obtained somewhat spoiled the battle tactics (if I had known, I wouldn't have taken it). Well, and the final boss, as is typical for the author, seems "cheaty" to me (he creates darkness, and nothing works against him). I had to go back for paladins who dispel dark spells. By the way, after all the reports about disappearing castles, the upper-left one always remained for me – the transformed elven castle (is this not a bug?). Overall, I liked the map, so my respects to the author.
Thank you for your feedback. The castle bug will be fixed.
