It was a long game with several saves. It seemed like my opponent was always far ahead, and I was barely managing to gather stats with my units, and almost all my creatures were level 1, with only one level 2 creature. I gathered what I could, put a Knight in my inventory, and, waving my hand, attacked Tant. And I won, unexpectedly for myself.
Thank you to my opponent for such a great game and for their patience!
