Lode Runner 2 Credits Level

Sorry, I don't have a walkthrough, but here's a map of a path you can take.

There are some very tough spots (unless I'm missing something), in particular "Mike Terpstra", "Paul Gorman", and "Craig Vinet". I haven't found any way to avoid making two trips through the left portion, though you can delay the second trip (to get the beach ball) until later.

Here is a copy of the image below without all the ugly lines and arrows on it.
