So you can use the CoreWindow.KeyDown event to handle keys:

public MainPage()
{
    this.InitializeComponent();
    Window.Current.CoreWindow.KeyDown += CoreWindow_KeyDown;
}

private void CoreWindow_KeyDown(Windows.UI.Core.CoreWindow sender, Windows.UI.Core.KeyEventArgs args)
{
    switch (args.VirtualKey)
    {
        case Windows.System.VirtualKey.Left:
            //Go left
            break;
        case Windows.System.VirtualKey.Right:
            //Go right
            break;
        case Windows.System.VirtualKey.Up:
            //Go up
            break;
        case Windows.System.VirtualKey.Down:
            //Go down
            break;
    }


    //In case you want to check for Control + Key:
    var ctrl = Window.Current.CoreWindow.GetKeyState(Windows.System.VirtualKey.Control);
    if (ctrl.HasFlag(Windows.UI.Core.CoreVirtualKeyStates.Down))
    {
        //Control was pressed

        if (args.VirtualKey == Windows.System.VirtualKey.W)
        {
            //Do sprint
        }
    }
}
