Very nice idea! Having specific parts of the world move time forward is a pretty unique take on the time theme.
Although the isometric style is nice, it made moving with WASD a bit confusing at times, and it was also difficult to tell if I was in a light or not. I found myself falling off of edges at times when it felt like I wasn't so close to them.
I couldn't figure out how to get to the lever behind the bullet section, I assumed I needed another button on the wall like the area before, but I couldn't find one.
Overall, a nice idea that could be expanded upon!
