So I saw this game quite a ways back, and recently decided to download and try it out. HOWEVER, after downloading from the Windows 64-bit Media Fire link, unpacking the file, and attempting to run the game I receive an error that a file failed to load. When I followed the error to the location of the file (mono.dll), it did not exist. Help? EDIT: I was able to get past the issue by finding a version of the game available for download on a different site, but there is still the issue that neither of the downloads linked by PRO for Windows 64-bit are working.
