Lillie,
What a wild and tricky ride!
This was a great dedication to Bob, who himself, a very creative craftsman.
First part took me the longest, but I solved it without any hints.
Now, looking at your picture, I see that my solution is exactly the same.
So, I think we can be sure there's only one solution to this level.

And like a few others, I found this much more perplexing than "Enter the Dragon".
Two Enthusiastic Thumbs Up!!!
EDIT: My above comment about " only one solution" refers to the first section with the four boulders.
