More fixes, cleanup, background music

I've been reading feedback here, and apparently someone lifted the game from here and made a version on a separate site, tried to read that feedback and reported bugs too. 

Many have reported random lock ups, I found a possible solution for this, there is a bug in the core game engine code that I think might be the issue. A user provided a fix and I am trying that out. I HOPE it fixes this issue.  

Changed the way a few of the game scenes worked, added in more hints and helpers. Really appreciate all the feedback as I try to make this a playable game.
