Hello Shinra. You need to have JDK installed (OpenJDK if i recall correctly?), download game archieve, unpack it with proper tool like 7zip or winrar or something like that. And use console to run it java -Djava.library.path=native/macosx -Xss50M -jar lewdmaze.jar
so.....I feel stupid...I found out how to open it, go to the files of the game, click on the java thing and it opens the game. Christ lol it was simple
