Not sure about the mech and maybe a better way to operate than i used. Looks very complicated for not achieving very much and balls can get in the way of the draggable. Looks good.

@ridgerunner you probably did it right.
Just make sure to drag it up gently, as there is a hidden lift behind the draggable that closed a 'gate' to prevent incomming balls from falling under the dragable.

To be honest, I wanted to do i more with the balls, but eventually decided that anything extra would do more harm than good to the level
Anyway, thanks for playing and rating

At first,I was a bit confused with the gameplay but I think that I understood the "mech"...& Was FUN ...& the design,as always,very nice! Thanks for sharing @Sculron

@delator77 thank you for your always enthousiastic comment.
I agree that this level could be confusing. I made this level several months ago, but I wasn't satisfied with it at the time.
I recently changed a few things to make it more interesting, but it's sometimes hard to keep in mind that others don't see what you wanted to do with the level (the creator ALWAYS knows what to do or where to go to complete it)
Anyway, thanks for the rating
