I'm super glad I finally did it :)
For a moment I wasn't sure if it's even possible to get 'Zero Deaths Bonus' on every stage. Levels 8 and 12 were super annoying, since there is no way to get rid of the rockets and you are not able to practice each segment separately since these will be gone after dying.
Also, for level 12 I had to use an alternative secret exit (I don't even think that the other path is doable).
Enjoy! :D
