Love this game!! Would like to see more level if possible.
Here is another solution that without intersect and with one of the shortest path (6).

Love this, I noticed my solution was much longer than yours, so I tried to make the longest path possible without overlaps (14)
There's only one node in the middle doesn't add to the length. Pretty sure 15 is impossible so this is literally the worst solution.
