Adding support for MacOS

• We have added support for both MacOS and Windows computers now, which means you can enjoy our game on major computer systems out there!
• We have also built-in support for Dual Shock4s, Xbox controllers (or any controllers using XInput) and standard keyboards.

The two features shared above simply mean one thing: you don't need to take sides to enjoy our game. Windows or Mac? No need to worry. Keyboard or controllers? No need to worry.
