This package is missing a dependency on qt5-qtquickcontrols. Without that, it loads to a blank window. Running it from the console shows: file:///usr/share/khangman/qml/main.qml:22:1: module "QtQuick.Controls" is not installed import QtQuick.Controls 1.2 ^ file:///usr/share/khangman/qml/main.qml:23:1: module "QtQuick.Layouts" is not installed import QtQuick.Layouts 1.1 ^ I installed qt5-qtquickcontrols and it works now.
qt5-qtmultimedia is also missing from the dependencies.

I'm going to be rebasing stuff to 15.12.x releases soon, and issue updates, the fix will get included then. Thanks again for your report.
