After a lot of questioning in ICQ, Kasha (thanks to him) gave me Kryvoruchka's contact information.
After several attempts to launch Heroes over the network, and after downloading Hamachi, it turned out that I had the wrong version of Heroes, so I had to reinstall everything and start from scratch. Thanks to Dima for his patience and help.
After a long struggle (about 20 minutes), I finally played my first game with him. After 112 turns, where I was playing as an Elf with Mephala and suffered losses of 14 centaurs on the Pokémon map, I took a Castle and was preparing to take another Fortress on the other side.
Kryvoruchka said that he had a small respawn point and the exits were guarded by vampires, another exit had a hundred centaurs, and a third exit had a few titans.
At the same time, he was playing as Inferno with Omela :D.
So, that was my first attempt, and it didn't go well.
