Raven's Despair

Finished the map in 116 days; the second half was quite boring, just accumulating troops to defeat all the human enemies, which was made tedious by chasing after the weak attackers from the portal. I also didn't like that you can't hire more than two heroes. The final enemies didn't pose any particular problems for a well-developed Gotia. But for a first experience, the map is not bad, and no bugs were noticed. Thank you for the map.

I'm on my phone, so it's like this.
Thank you for the Walkthrough and feedback; it seems it turned out to be quite easy after all. I created this portal to somehow diversify the process when I realized where things were heading; I will make these runners stronger, as well as the final boss. You can also send me replays of the last battles in a private message; I'll watch them when I get home.
And, technically, this is my second experience in mapmaking; the first was the map "Counterattack," but it was made entirely by copy-pasting scripts from campaign maps.

Yes, and also - was the reinforcement quest working properly? It was created to stop the runners from the portal later on
