#### Game controllers / joysticks aren't working!
Windows only permits certain game controllers and joysticks to work within
WinRT / UWP apps. Even if a game controller or joystick works in a Win32
app, that device is not guaranteed to work inside a WinRT / UWP app.
According to Microsoft, "Xbox compatible controllers" should work inside
UWP apps, potentially with more working in the future. This includes, but
may not be limited to, Microsoft-made Xbox controllers and USB adapters.
