Flow Problem - major update

This is a huge update compared to the original upload.

Firstly we have the addition of music and sound effects.

Then we have a few QOL enhancements (you may or may not notice them, but they're there!!)

Finally the main code has been completely refactored to improve performance. I can't tell you how it will affect your specific system, but on mine it maintains a pretty constant frame rate of 60fps, whereas the initial build often sat between 45-50fps.

Whether you've played it already or not, I hope you enjoy the results of this update!
