With 108 ingame hours and 20 rooms, 10+ girls there are some things i noticed:

1. random endless scrolling to right after a few hours, might be related to wine (Linux), always happens in interaction room.

2. Futa was born even though i didn't research it yet on purpose (not my kink). Though i do think that should be a setting in main menu, would make it easier to implement in spawning rate too.

3. 8/10 girls are always crying, "Mind" status is always too low:

• Maybe i didn't find a way yet that already exists, to craft your own version of that "Mind" increasing brew i found once(!) in 100 ingame hours in the store.
  • if not, there needs to be a way to do so
  • need to have more Mind increasing items in store
• Training room sounds like a good idea to me,you could prepare your forces for the next invasion (more content for not much work) and the training would keep "Mind" up. About the counter from voidtninja:
  • I found no option for summoning via Altar
  • Can't constantly have 2/3 of your forces in the outer world to train to keep "Mind" up
