I'm stuck. I found old notes 1-7 and it seems to have triggered *spoiler* the shadow guy in the bottom right of the mine, but there is no way to get to him and there does not appear to be anything else to do in the mine.
Don't mind him, you have to go a bit up and to the left till you find a note that triggers a choice dialog. If you have already found it, keep going left and up to find another event!
Two of the notes I picked up had a choice leave or stay option and I always chose Stay. The only other event I found is the exit which just has Alexia say "We can't leave yet." Is there an 8th note I missed?
2 notes? ah... it should be one, I'll check this bug... well, after you stay a new passage opens, to the left, and then up, and to the right, you will find a bigger hole, check it. It's a little below the exit.
Got it. Had not realized the big hole could be interacted with since no items other than the notes triggered events. Maybe Nadia could toss a note out of the hole after we read the final note and that could trigger the rescue.
Thanks for taking the time to help me figure it out :)
