Great submission!
The chef's name (Emil) sounds like and the portrait looks like a man but the character model looks like a woman?!
The transitions between the story beats could be made more clear - it's just a very short black screen now. I'm assuming that you did it this way because there are no walking animations and you position the character models where they need to be. However the first two times it happened it seemed like a technical issue. It would be nice to write some notice and prompt the player to continue.
I encountered a problem that can be expected in a free roaming narrative game - I searched through the entire bunker early including examining the door to the Utility room. Therefore it was a bit unexpected that I needed to examine it again to trigger the next story beat. Maybe you can include logic to check if the player found it and transition to the next beat automatically?
I got to the point where the engineer changed the fuse, the lights went out and it seems there's nothing I can do to advance to the next beat. Please advise. I would like to play through it so that I can share my full impression.
