Hmm...i am bad with ideas but... maybe a more mechanical way of feeding or lewd fun like portals or droids?
the feeding system is already planned to include automatic feeding system but that is once movement starts to become a problem, movement wont ever be completely removed but once movement issues arise a automatic feeder will be installed on ship that will prevent you as the player from needing to get up to eat, with a portable version for when away from the ship, as for portals and droids, portals i might include but droids not so much, since i wanna try and keep the characters human as much as possible though for the Mass Effect DLC, EDI will be present and since in Mass Effect 3 EDI gets a android body, she is technically a droid but nothing can happen with her since she is dating Jeff “Joker” Moreau, hell even the aliens will be exclusively from other franchises and only available in DLC since i don't have anyway to include visuals and i am bad at coming up with names so coming up with names and being able to give the game original aliens concrete appearances instead of making them ambiguous and having them look different for others since giving a rough example with text won’t guarantee that everyone envisions the exact same thing, even giving a detailed example with text might still not guarantee that it looks the same for everyone, also i apologize for the late response, been unable to focus on the game since i can’t find the motivation to continue, i want to but every time i try, i end up doing something else.
