Should work like a regular executable file. Just take it out of the zip file and then double click on it.
You may have to install Java if you don't have it already: https://www.java.com/en/download/manual.jsp
This is an old game I made way back in high school, so I'm not adding any new features or support for it, but thanks for your interest!
Sorry, this is a very old project from High School, so I am not adding new features to it. If you want, you could use a software like Joy2Key to bind your controller to keyboard buttons: https://joytokey.net/en/
