Thanks for the feedback! Glad you're enjoying it so far. I do have a Patreon that I'll start promoting next update in the hopes that people like the project enough to support its growth.
At the moment, dialogue choices are either only for flavor or affecting character relationships. Rather than changing the course of the story, they're simply different ways to justify going in that direction. I'm hoping to give players more agency over the story in the future, but the main story will follow a planned course for the most part.
There are a few options that increase disdain at the moment, but they'll only have an effect in future updates. As for the text auto-scrolling, that was a stylistic choice that I'll probably end up changing, since it evidently can seem more confusing than effective.
Investigated that crash with Varsha and fixed the cause on my end, thanks for letting me know about it!
