Hi! Thanks for the feedback!
Could you please provide some examples of what you found to be stiff? We are aware of problems with dialogues from early routes (Sonya, Seraphina, Yun and Freja) — they were written a long time ago and will be rewritten in the Overhaul Update.
Right now Young (our story writer) writes in English from the get-go instead of relying on the help of a translator, like he was doing early in the development. It allowed for a much better control of the flow of each line and hopefully had a positive effect on our later updates.
So if it's the early stuff you're bothered with — it's okay, we're working on it! But if it's the dialogues of Ava, Reina and Aurelie, then we'd like to see what exactly you found to be broken. Though we will still skim through those parts just in case once we get to updating older writing.
