Aaw yeah this one is a bit tough ahah. There’s the secret ending optimal route in the description if you get fed up and want to see the layout of the level.

Ahah sorry it’s so messy. Basically you drop down, go right, go up, jump all the way to the left, drop down, go right and wait for the ghost to pass over you, then go to upper right via the middle, drop down and finish the run going left into the tunnel.
Edit: Just noticed thats not optimal, there’s a better route, that’s just how I usually run
Edit 2: Updated the route and image to be more readable
