Hey, thanks for checking it out! I'm glad it was a bit better! Sorry for the late response here.
That is actually a bug, Baldric is supposed to unlock the gate and send you off, but the demo ends there anyway. Thank you for playing!
I will be making some more improvements with a new version soon (I think it will be better if Baldric joins you in the dungeon, for example), but it's good to know I'm getting closer to getting the balance right.
In the next major demo release, eventually there will be much more content like an entirely new area and progression of the story :)
