I hope they add m@strubation/self playing stuffs for both player and the partner. I also hope the game shows player character when we customize them. Also, if you choose female characters as a player, it's automatically becomes futa. Hope they add futa as an optional in the customize. Because I also want to try yuri since it's already have yaoi. Futa also best, so please don't remove futa. It will be perfect with this things in this game.
(Extra: Hope dev make the characters bit realistic. Like adding jiggly effects for both b00bz and a$$ while having s€x. Also, want original hair style for xinyan.)
This is only my idea.
