Rush: Final Version

It has a name now; Rush and its at its final version. It has a large variety of new things I've implemented(including a secret) which is listed below:

Sound effects

muting

retro effects option

2 new game modes

highscores

extra settings

And a lot of internal development

Most of the development has been boring with some UI fixes and sound design implementations that I had to add some extra features like highscores and more pleasing post processing.
