Playing with godot3-runner and the project taken from github, I still get stuck in a dialogue-loop on the rocks. I think I managed to get out of it once with Rocky, but couldn't repeat it.
And when you reduce the audio volume and open the options view again, the slider is reset back to maximum (the audio level won't change though, until you change the slider's value again).
Movement through the cave was smooth, my gamepad worked fine.
There's not much to see regarding screenshots for the dialog. I push the button on the controller to advance the dialog to the next bit and at the end of the other rock talking I am inside the dialog again immediately.
Actually, come to think of it... when I approach the dialog starts automatically without me having to open the conversation. I'd think that's the actual issue...
As for the audio-level slider, you would have to keep its setting somewhere in a global variable and when the dialog is opened initialize it with the saved value. Or maybe you could have it check the audio player what volume level is set.
