Yes I found the bug, thanks again because I'd never have found this! There is a rectangular trigger at the top that sets the platform to collide, and I had accidentally left an old script on it meaning that when you leave the trigger the trigger itself becomes collidable. You had flown out of the top of that trigger. It was indeed the idea that you could give yourself an extra boost by clicking quickly, to play with the physics. Though I tried loads of times and still didn't manage to get as high as you did and leave the trigger! Good effort ;) - I will say though you have completed the game, there's just one dialogue after that and it's done. So good job! :) Thanks again
