Thanks for checking it out, and for the feedback!
The sync between the text-to-speech and the auto-advance should be about the same anywhere, but it's super dependent on settings. It actually advances based on the Text Speed of the dialogue, which roughly lines up on my machine (and yours, it seems!) but really could be different for anybody. Fortunately, adjusting the Text Speed would be an easy way to line it up if it is!
Appreciate the insight it on the menus too, I agree. I've had some great feedback in the Discord too and I've got the next version in the works already. It's gonna have better callouts for initial controls, and also a self-voicing-specific control overview at the start of the existing tutorials (Battle, Shop, and a new one in the Player Menu). A bunch of other stuff too, but I think that should be the biggest help.
I love hearing it called polished! I'm really trying to get this thing as clean as I can!
