Hi, just trying the demo out before I think about buying the game. There are some issues I thought I would share:

• There's some overlap with the UI that causes it to get into a bad state. Pressing Esc to get out of Inventory led to being stuck in place. I pressed Tab again and was able to move again.
  
• Same as above, but this time from the "Read" overlay - could not get back to a movable state, so had to just restart the whole demo. WTB save, but I understand it's just a demo...
  
• Got into menu to exit at the same time the Read overlay was up on the Taro card hint letter (don't ask me how) and could not hit the button for exit; after closing the read overlay I was able to hit it. So it seems that the main menu is not in the highest UI layer. I would recommend using a state machine for the UI so that there can only be one high-level action being performed at a time to avoid these kinds of issues.
  
• After getting Lantern, could not figure out how to use it. Some help text would be helpful for people to get familiar with the UI.
  
• Game froze in the Historical Society house, right past the hallway with the stuck door in the "dark area".

Would love to take another stab at it and I realize the Demo might not be on the same branch as the main engine, but would be nice if it was more representative of the final gameplay as a sales point.
