At least it looks like a fighting game, with buttons labeled Kick and Punch. Upon closer inspection, we find that it's a JavaFX version of the classic Pigs dice game, co-created by a JavaFX developer and a graphics designer.
Graphics designer Jonathan Wei used Adobe Illustrator to create the artwork. The JavaFX Production Suite was employed to make it very easy for developer Jim Connell to use that artwork from JavaFX. To help you learn this process, Jim has created an excellent tutorial that shows you how this game was created, walking through the [small amount of] JavaFX code contained in the program.
Regarding the Kick and Punch buttons: They don't seem to be operable, and I suspect that they reflect the aforementioned guys' twisted sense of humor :-)
Thanks for this excellent resource, Jonathan and Jim!
