I always enjoy experiences with minions with minds of their own; I went from cheering on my favourite minions to despairing at the one (who I have named Stanley) who kept wandering about on his own!
I was worried it was going to be too easy at first, as one adventurer is very easy to dispatch, but once they started coming in twos and threes, I felt the pressure immediately.
Ultimately undone by an adventurer graced by the gods; despite giving my minions ample opportunity to dispatch him, they practically welcomed them in. Some means to deal with bad luck (like a long cooldown attack from me, the lurking dungeon boss-man) would help alleviate these scenarios.
