I've made a few solutions of this level, I reached $1246. Then I decided to check my record for this level at the website.
I saw that the record is 1452, and started thinking... that is 1 metal sheet, 2 metal bars and a piece of rope. I draew these elements to the level and started to search the solution... but I didn't find any Then I gave up, went to the website and downloaded the solution.
Then I started the solutoion and for my suprise I saw that some of the elements are extremely powerful without any tension applied to them. I think this is a bug in the game. What do you think?
