8:01 A personal best. Good that it happened today, because I was about ready to give up when the easy puzzle took me more than 6 minutes. I'm not quite sure what was up with that.

I love butterflies! Good idea to have a special park for them.

I don't do time but I found this one fairly straight forward. I guess it's all to do with the way you approach it and whether you spot some doubles or triples early in the piece.
I do Easy 1-9 with no possibilities,Medium with no possibilities and try for 1-9, and Hard and tough with 3/4 More...

Unless that's a joke, um.. the butterfly is black with yellow.
