Startmenü, fremde Figuren und Statuszeile

Das Startmenü fragt nach dem Namen und bietet allein spielen, die Welt
öffnen oder beitreten. Die Figuren der anderen Spieler gleiten zu ihrer
neuesten Position und tragen ihren Namen. Die Anzeige füllt Werte in
Meldungen ein und hat eine Statuszeile. Die Texte für Menü und Netzwerk
gibt es auf Deutsch und Englisch.
