There are two more route planned for the game, however, they are not yuri focused.
Violet and Kate are the main yuri focused routes.
Oh, I see. That's a shame. I liked the game a lot and quite liked the routes of both girls, as well as the interactions, dreams and events that contain yuri in it, even though said content is somewhat lacking and there isn't as wide a range of options as the other routes and interactions. Still, thanks for answering my question.
