Whatever is enclosed in the single quotes wil be interpretted literally, so you either use the quotes or the escape character. I think you should use only one set of quotes or if you are going to use the escape character, you have to use it throughout the whole path wherever needed, i.e. /usr/local/games/Superbrothers\:\ Sword\ \&\ Sworcery\ EP/lib
