Hello, I really enjoyed the game demo and I understand the comments about how disconnected the protagonist seems.
As someone who greatly enjoys horror games (being a big fan of the Silent Hill series and others), I think it would be interesting if she had internal dialogue regarding her actions.
For example, right at the beginning, after the first puzzle, when we have to be disinfected.
A "What, what's happening?! Oh..."
Even when we have to crawl through the ventilation shaft.
"...Please... let there be nothing ahead..."
I even thought,
"Would VA be a good idea?" But honestly, I feel it's unnecessary. With dialogue at the right moments, showing the emotions the protagonist might be feeling—fear, happiness, discomfort—we as players understand her perspective.
