Terrible situation, didn't take a restart because of the hidden Black Knights near the castle (which I couldn't break through), I had only a small pile of gold and 2 chests, and my army consisted of 55 skeletons. The secondary mines were guarded by 10-19 mages, 50-99 lizards, and 20-49 demons. In the end, I reached the snowy secondary mine at 121, started taking over the crypts and raising skeletons. The opponent arrived at 125, broke through the lizards, captured the main mine, and at 127, he caught up with me and killed me in the secondary mine.
Thanks for the game!)
