Use browser to download archieve (not Itch download app).
Download windows version if you have issues with Universal (some unpacking tools like old Winrar may strip Java games into pieces).
Make sure your antivirus tool is not blocking stuff either~
No, not really. WIN version has huge exe file inside (its auto installer).
Universal version should have already pre-installed batch of files inside, if you unpack it, you should see inside Jar, exe and bat files. All three should be able to lauch the game.
How is your game folder looks like after unpacking, can you attach a screenshot?
The game folder was empty. When I unpacked the zip file, it scattered everything throughout my computer's downloads folder. I had to create a folder and collect everything in to it. That was the universal version.
The WIN version only had the three xml files I mentioned before.
But it is working now anyways.
