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.
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.
4) I'll add more reinforcements.
But what's the point of the development limit?

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.
