I think the 3d character designs are a unique choice for a visual novel! Is there any way there can be a web playable version of this demo? It would allow people to play using mobile devices!
If you're using Ren'Py, then you can build a web distribution using the launcher using the buttons shown in the red box. You should definitely experiment more with the engine as you develop your game to get a real sense of all the tools available to you. There's a lot you can do with the logic and math around the default systems!
