just a suggestion but perhaps at the start of the game you should allow the player to choose between the characters being biologically related or step , perhaps that would be hard , but some people may be uncomfortable with the idea of incest . disregard this if it is difficult or stupid , just a thought , thanks for the had work .
step or biologically won't have to alter art , but i understand it will be difficult to alter , but some people may be reluctant to play because of the intense incestuous nature of the game , including myself mind you , therefore i personally would appreciate , but i must also state that it should be low priority for the author as i am sure he is busy , and my suggestion will do little overall .
