Game Feel Galaxy Platformer Redo

I made the following changes compared to week 2:

 - the background speed changes when hovering over buttons and when sliding the volume sliders

 - the different menu screens now have transitions between them

 - the buttons have a different shape, which rotates when hovering over them

 - the components of the 'controls'-screen now look less like the clickable buttons

 - changed the lay-out of the main menu screen to be somewhat more playful

 - the values of the volume sliders of the main menu and the pause menu correspond with each other

- when pressing [escape] in the settings screen or the controls screen of the pause menu, it will go back to the main screen of the pause menu instead of directly continuing the game
