I solved my problems with the FPS controller and other smaller bugs simply by virtue of experience and understanding shorthand controls.

My problems with the audio remained, however.

The playmaker feature actually seems more intuitive than I would have imagined. Then one thing I'm still having problems with is the iTween animation; I keep trying to have the gold rise and map to the sphere I created when I move into another sphere I created. It didn't work that way.

I'm not exactly sure where I messed up with that correlation, but it made me want to rip my hair out trying to problem solve.
