The bridge: I went to do it proper, and by that I figured 'using the level'. I don't know if that was the creator's idea or not
I fixed your level 3.5, you used 1 component too much.
I don't know about the first level, it looks quite tweaked-out.
Your level 5 is nice, I missed the obvious rope+sheet hits bar...
I tried cheapening your level 2. I failed.
