Just realized that it's impossible (as far as I can tell) to finish this if you fail on the last jump and cause the yellow platforms to disappear. I would change it, but this was uploaded for an assignment that is now closed, and I fear that I would get minus points for uploading a new version after it was due. So just refresh the page if you really want to finish it and manage to destroy those last yellow platforms.
