Loopy is easy, once you get going. When I was in school, I'd print off pages of 20x20 loopy puzzles and do them in class. In pen, because I'm cool like that. It's so addicting! And I don't know why!
I also beat "tangle" on 30-points. I think I took a screenshot somewhere, but I lost it. Ohwell.
That's still the best puzzle pack!
