DrLuke, that is really awesome! I myself work on a “marble” game but with different core mechanics. Yours look way better, but if you are interested in a sneak peek, I would appreciate your input 
I noticed that there is a small bouncing when the ball changes the gravity upside down on the rails. You could fix that if you place the upper rails closer so that they are almost touching the top of the ball before/when the change occurs. In that way, you do not have that bouncing, keep the same speed and the transition will look smoothless without touching the blueprint 
Keep up the good work, your work is a great inspiration to people like me!

I’m really glad you like my work!
I think your idea is quite neat, I’m interested to see what you come up with!
