I purchased the Windows version of the game (I have a Windows 10) back when it was on sale, went and extracted it, but the game doesn't run no matter what I click on. I've tried clicking both the run_win file as well as the .jar. For the former, the black command prompt window will appear for a few seconds, then briefly disappear and then nothing will happen. When the jar file is clicked on, the cursor indicates that it's trying to run the program (I think), but there's no window that comes up or anything.
I haven't had trouble running .jar files for other games or programs, but for this particular one, it just isn't opening on my computer. :(
