Cool idea! I was a touch confused was to what was going on at first and just kinda darted in a radon direction towards a star. then upon losing my ability to spring it clicked, I had screwed up the order of star collection.
Even then though, you'd put in failsafes so it wasn't a lost cause, even with just jump left I got all 5 stars and just abouts made it to the end.
Nice work!
