This is a swing applet version of DarkworldPHP, which doesn't use a deprecated JAVA API. You can view it with the AppletViewer from the Oracle JDK. Change to the applet's folder and start the AppletViewer with the command line tool. Use the .htm file in the applet's folder as parameter.
Use cursor keys to select the flying direction and return to shoot.
My game installation was not fast enough. The DarkworldOnline Application with players connected over internet (WLAN) was fast enough.
