Relax! Demos and playtesting are (at least partly) for catching bugs, the system is working perfectly :)
The demo is pretty good. Like you said, you've focused on polishing existing content rather than adding new content, so the changes are a bit subtle compared to the previous demo. I like the changes you made to the health/armor/conversation systems.
The world still feels alive, like there are other things going on around you and you're just a minor participant, there are mysteries to solve, and maybe there are things you won't even see in a single playthrough because of the different paths you can choose.
I have no idea what the Elder's real name is (probably not in the demo I guess), and I don't have enough money to buy Dajit's monster advice (again probably not enough money in the demo), so there's exciting things to look forward to in the future. I wonder what happens if I choose all the agressive conversation, or if I choose to joke around with the innkeeper despite being told not to. I want to play a few different games choosing all the different options. I expect if I choose to fight the the goblins then I might die. I'm actually scared to discover what's hiding in the ruined town, the writing is so good.
I guess from here, you have that mid-development part of adding new content. People often say this is the slow boring part of game development :P but also it adds the bulk of content which players enjoy.
