Valley of the Marauders

It's strange, I was playing in a clockwise direction, completed almost all the tasks, and then, after several attacks on my castle around the 10th week, access to the green "God of Thunder" opened. On the way to him, I defeated "Daughter of the Heavens" and a couple of similar types, and as a result, the game ended (72 days), but not all main tasks were completed (?!). Well, never mind, I left him alone and went to take the remaining blue castle (the 4th, not counting my own) in the lower left corner. I took it, went down further, and met a green weakling, defeated him, and then the game froze (?!). In general, something is wrong, and also, in my opinion, the game lacks dynamics and intrigue. I also didn't quite understand why the main character needs to "Solve the Secret" (at least there's a mentor). Nevertheless, thank you to the author for their work.
