Revived

On the very first one – I started playing when there weren't any others yet, and I don't feel like replaying it for the fourth time.

The redhead needs to be strengthened in stages 3 and higher.

... Maybe completely ban the Temple of the Underworld?

It's not worth it – it will destroy the nuance that makes the game interesting, but if it were possible to build it only after completing some kind of quest, that would be a good idea.
