this works for me:
up/right twice and down/right once for first two walls in first stage but the first start normal but bunny hop and start spamming same pattern and increase in speed as you go you might mess it up a few times to get the bunny hop right but doing so will allow you to phase threw a few stages and then just comes down to timing and luck and using the forward as much as possible to try to phase through as much as possible and can use the same way to build speed at any point
