Holy guacamole, this is great! I love that you've taken the "Dying to progress" a lot of games have and took it to the next level. You're not using dead bodies as platforms, and as such I don't have to repeat massive sections of the game everytime I want to progress, instead I move the orb, and the game dynamically follows me, its really cool!
I can see why the screen stays still, but the screen transition between up and down of some segments can feel a bit off sometimes, but other than that a really great game, I'd love to fight a boss or something with this mechanic, see where it goes? Possibly conveyor belts or something for moving the orb.
