When I first uploaded Dungeon Hoard I did so while having the wrong jme libraries set in the project properties. This was a mistake I made on Friday when I started a new project on Friday and didn't use one of my other projects as a reference. Long story short it worked fine in the IDE but the resulting jar would fail to run. When I uploaded to Itch I never bothered to check the executables, they've always worked in the past XD I pressed publish and took a nap. Woke up with my Wife asking to play the finished game, went to run the executable and nothing happens. Half an hour later problem is solved, correct files are on Itch, my game works now! Sorry for anyone who gave it a go, Lesson learned.
