Thanks for playing! I'm very glad you enjoyed the game! The next update is currently in the works and there will be more coming soon! Please look forward to it!
I'm afraid not. There won't be any sexual relationships between close relatives and/or individuals who share blood in the game.
Hello! Yes, you can have a playthrough with only one love interest/romance partner! Although, I must warn you that I'm still building the game up, so the game is still in its early phase. Therefore the mechanics for the love interests in the game are still being built up. The "locks" for romance paths will be added much later in the game's development.
