Sorry, it does have a key change. I couldn't resist because otherwise I was afraid it would be too monotonous. Another way of thinking about it is that you play what you just play but two frets lower on everything for C dorian.
Sometimes I was making mistakes with it, but it still kind of worked because it is quirky to begin with, so have fun!
I decided to go with no color coding on the scale this time because it is modal. That is why I just tried to make it look cool, similar to how websites sometimes have a dark mode feature.
