I tried many time... in vain... I gave up now ^^'
Hello there!
We are sorry to know that the scene was a little too difficult. We will definitely consider making it easier in the future.
But in order for everyone to enjoy the game we have made a Save File for those who couldn't pass that scene. It is made immediately after the run is over, just load it and the story continues after the running scene: https://drive.google.com/open?id=1fNimuJPmERSWllQHWoKfmRyncJm4s9WG
