I just uploaded version 0.1.2 of the demo on all available platforms. It's a small update with some typo fixes, but mostly to fix a specific bug:

• Change the surgeon's bag from a consumable to a regular item
• Fix a set of late-demo conditions with said item that can prevent completion
  

It's not likely many players would have run into this, but if you found yourself stuck toward the end of the demo after using the surgeon's bag to heal a wound, this should correct the issue.
