Thank you for the feedback!

Near the sawmill, where you need to save people from wolves, there's a village nearby, but it's not functioning... Also, it would be good to have a hint after discovering all three "centers of resistance" – telling you what to do next and where to go. And there are too many undead; you fight, but you can't replenish your losses with the gold they guard.

1) Well, according to the plot, there's only 1 peasant living there, not 20 being born every week. And the sawmill compensates for the gold (as do all other collectable resources) – all the factories are working.
2) Finding these centers is an additional task, while the main quest line remains open.

One of the drawbacks is that the computer just waits in the castle, not moving. It would be better to strengthen it and increase its aggression against the player. The player should either get a castle or have more diverse reinforcements scattered across the map.

3) The computer waits because the player doesn't have a castle. And all the resources are there for the player... In general, the AI is unnecessary here.

4) I'll add more reinforcements.

But what's the point of the development limit?

I wanted to make a sequel to the map and start with this limit, but now I've decided not to... So I'll remove it.

I've re-uploaded it. Regarding the changes:
1) The hero's maxlvl has been removed.
2) The reinforcements remain in approximately the same places (where there is no undead), but there are now more of them.
