The rats "power" is super inconsistent

[Soulkey]

Sometimes a small swarm of rats can break through castle and building walls.
But other times some dinky remains of a wall can hold off a gigantic flood of rat.

If they ever make a sequel I hope they will be more consistent, that and also tone down the protagonist's mumbling a bit.

Can't say I disagree with that last bit. We're supposed to be sneaking past this armed guard. Probably not the most appropriate time to provide commentary on our current predicament.
