Hiya! Sorry for the delay, but so far I haven’t made much headway on this since I’ve been away from VN development for a bit. With that said, choices are still possible using the usual mechanics, but they aren’t thematically tied in woth the chat system.
It would indeed be nice. I don’t know when I’ll get back to developing VNs, but if I do and end up updating this to include choices, I’ll make sure to publish it and let you know!
