Netting - puzzle about Dots by Oleksii Kudriashov FREE

Netting - puzzle about Dots comes from Oleksii Kudriashov.  The object is pretty clear from the images: find a connection between the start/end points for each color without overlapping.

However, things get complicated.  There are bridges where an intersection can take place.

Also, sometimes a midpoint of color is given. But which of the 3 blue points is in the middle?

I've been stuck on level 36 for a long time.  There are no hints. No answer key. 
This game is much better than I anticipated.
