I just found this game and already sank six hours into it! Hard to put down.
I noticed a few bugs. Certain cards that I believe are supposed to be removed after they're played stay in the deck. For example, card where you become a toy of demons stays in the deck, and keeps adding duplicates of card for the demon related events. I'm frequently getting the card where the adventurer wonders about leaving three or more times in a row, too. I'm not certain what card adds another of those cards to the deck, but I'm getting that a very disproportionate number of times. After a while, the majority of the cards played are either demon events or the same adventurer event.
Is the feminization ending finished? I ask because I chose the option that said it would lead to that ending, but drawn no further cards related to it. Choosing the option to get an exorcism also seems to do nothing.
When I choose the option to have the guards remove the two succubi from the room, it doesn't affect my army at all.
