Does it just use default browser TTS or windows one or can you install separate ones? I glanced through instructions and haven't found info on this specific thing, either way this could be interesting even if voice is kinda robotic, voice packs for skyrim NSFW mods honestly were a game changer for me. Anyway thanks for sharing I might give it a try.I've just released a Text-to-Speech mod for Twine games that I've been using while playing DoL for a while. It essentially turns the game into an audiobook and for me, it makes games like these that involve a lot of reading much more enjoyable. Hope it helps!
