I was checking on the other players solutions to the Unpossible level. I posted one a day or two ago, with the title "Mighty Push", and today I discovered that dav23ful1 posted EXACTLY the same design about three after mine, with the title "all mine". I am afraid that that title is not correct. He may well have come up with a similar concept (although I did not see one under his name), but I posted that identical design before he did.
What also irks me is that mine has a 3 rating, while his copy of mine has a 4 rating...Go figure.
