I've updated the game to Beta 4 and am in contact with your music guy.
The current music is just something I had made in the past to fill in, but I am waiting for the new music.
Beta 4 is out, however lots of the new content is for mid/late game (i.e the river and its plot), so up to you if you play past the first cave (when the river unlocks).
I only had a short time to explore the improvements and I've got to say it feels SO much better now. The only things that I noticed this time around was that the music would have some issues every once and awhile. Since I stuck it out further this time, I did find myself wanting a "back to base" option while exploring the cave. I wouldn't mind if that had a price attached to it either. It might be something to consider at least. Anyway, good job on the improvements :)
Glad you like it. The music thing I insist on though. It cut out multiple times and there was even 2 instances of total silence for 10's of seconds. I just wanted you to know that was my experience. Perhaps my slow internet is to blame? I'm not saying it is your fault, just that it happened and wanted to let you know.
