umm, im on windows 10 and ive spent two hours trying to open this game, and ive already downloaded it but it just wont work, so it would be helpful to know how this gets opened, thanks
Unzip it, if windows won't unzip it, you could download 7zip and unzip it. If you still can't get that far, it might be your anti virus being over protective. If it is that, it's entirely up to you if you want to allow it, to do that: Right click the file, scan with windows defender, then once its done go to actions and click allow, then start actions.
Good luck!
