If u jump right at the beginning and dash to the right then ur ur a tiny bit higher than the starting point. Because of that u can spam dash right at the wall and damage it 2 times. After that u dash ontop a pillor and derstroy the wall. This trick saves u about 1-2 sec. And its hard to get. Good luck!

Indeed nice one :3 I will be back :D
