I have the impression that this game is going too much towards cultism, maybe tone it down a bit? Because the game is okay but there are also people who don't want to have anything to do with it...
Worry not, nobody in the story nor the gameplay tries to build any cult in any form. It's just a bunch of lewd people helping a witch summon demon lords. Hence why every level starts from zero, with only a couple of units UwU
As for the demon themselves, they won't really care ruling over the mortal world, it being already a shithole.
And if I see any glimpse of a cult, worry no more, I have angels waiting to intervene and kick butts!
