First, you need your XBOX controller hooked up to your PC. Turn on the controller and hold down the sync button. Go to your windows 10 settings, click devices, and hit Add Bluetooth device. The category will be either "Bluetooth" or "Everything Else." Try the Bluetooth one first.

Then, to get the controller to work with the game, all you have to do is launch the game, and just press any button on the controller. Now your controller is ready to play!

It will be mouse and keyboard by default, so you'll have to press a button every time, but that's not much.

You can switch back to mouse and keyboard in-game by either clicking on your mouse or pressing a button on your keyboard, then the game will instantly switch back to using your mouse and keyboard!

That's it! You can switch between instantly! It's that easy!

Also, another bug fix I couldn't fit in the post:

I fixed the bug where both the purchase sound and the error sound play simultaneously when you don't have enough cash to purchase something twice.
