MonoShift V.4 Update!

Hello Shifters! 

MonoShift V.4 is here with a few changes! 

In this update we have:

• The option to toggle the Spacebar as the input key for shifting! (For if sticky keys is giving you hassle!)
• A new level, introducing a new feature: Rotating platforms! Yay, more challenge!
• Audio for when the player shifts between the black and white states
• Audio for when the player collects a key
• Minor UI fixes!

Thanks to all of the feedback that I have been receiving, MonoShift is slowly but surely improving! 

Thank you for playing, I do hope that you have fun! :-)
