Unicorn Empire

Good luck! If possible, please share your progress.

Thank you!
I completed the prologue; the story is interesting. I played on veteran difficulty and struggled for a long time to defeat the undead guarding the portal to the rune. Then I remembered that I had a cloak, upgraded Darkness to the maximum, and easily defeated the undead.
The map is excellent, there are no bugs, everything is working properly, and the story is interesting.

I started the campaign; in the second mission, the upgrade in the Fortress to green units only works if you already have upgraded units. That is, the most ordinary peasants are not upgraded. Is this intentional?
