Once an installed JDK has been checked for, click The game's executable .jar file to download it, which will then run as standalone when double- clicked in the file manager (equivalent to selecting it and choosing the menu bar's Open -> Open as JDK Platform Binary facility's associated option, if provided). Alternatively, or to allow for program recoding, it'd be necessary to modify a batch file by putting in the appropriate path for the particular computer's java.exe installation. To do so, extract the zipped folder's files, and those whose JDK installation is release 11 or later can make use of the Run.bat file after its path is modified by opening it in a text editor: double- clicking it for a simple rerun of the single .java source file itself with any revisions, as long as no .class files preexist in the source directory. Those keeping to earlier releases (who'd know this already) or who modularize with multiple related source files need to use the Mak.bat file to call Java's compile and run utilities with generation of the pertinent .class files.
