For those who wonder, this is not a virus, because it wouldn't stand on Itch.io this long if it indeed had malware in it, and it also seems to be a remake instead of the original application.
+ that, even the original version of the software isn't a malware anymore, since it was made originally for old operational systems and it's spyware servers are down for decades now, thus being available in Archive.org without being taken down.
