Apartment #69 is another promising 3D game. There is a non-binary character in

2D games I have enjoyed (for different reasons):
Otomaid @ Cafe (traps),
Roundscape Adorevia (one main character has tits+cock; some minor characters are non-binary),
Lilith's Throne (futa, I don't remember what else. You can change the gender of the NPCs though),
HHS+ (traps) and
Starless (futa). Last but not least,
