This is really cool! I played around with a similar mechanic a while ago (as an FPS) although I didn't get the world jumping implemented. Really impressive stuff.
Game itself is a bit on the challenging side - maybe if the camera zoomed out a bit more it would help... As you try to leap to a distant planet the margin of error gets very low. Possibly even a line that appears after a period of not moving (using valuable delivery time!) that shows where you'll leap to?
Really slick presentation, I liked the look a lot. Good job.
