I couldn't figure this one out for anything! I could get one conveyor stopped, but not both. I knew ol'gramma dogs were behind this, but I couldn't see them or what they were doing. I could sure hear them barking away in the background somewhere!! I finally gave up and looked in the editor - hope you don't mind Deanville - and I saw what needed to be done. Those doggies are very sneaky!
Seems like I went a little overboard... the idea was to create a puzzle that required doing things in a certain order, not make it necessary for experienced players to use the editor to solve.
Just completed it!!!!!!! That's the first of your 3 levels I have completed Haven't got a clue about your second one and keep getting splattered in your first!
I guess this level will keep my mind entertained for a couple of days. I am already playing it for some time and still no success. I'm sure there's a simples solution behind this that I'm not paying attention.
