Chris, I don’t remember trying to solve that level. Since it was created three years ago, I was probably on vacation at the hospital :) This level is in category medium, but it is indeed quite hard and tricky, it took me a couple of hours to solve it. I will give you some tips in a spoiler, ask if it's not clear.
- The most obvious moves are often to be avoided. For example, left green to the right then upper red down. - Place first the blue and the green on lines 3 and 6, then the other blue and green. It’s the hardest part and you can often be stuck. - End with the reds, it should be easy.
