Unity recently announced that they had found a security flaw in their engine. While they had mentioned nobody had taken advantage of this vulnerability, as they had discovered it internally, they still updated their engine to patch the issue and recommended others to apply their patch, which I've now done. I doubt there was much risk that my game would be exposed to the security risk, but I'd like to be a responsible developer.

If (for whatever reason) you decide to play a game over half a decade old (Christ, time flies), I would recommend you download the newer version which is practically identical to the old one, assuming nothing has been broken.

I have not done anything to the released public project files, as the issue was seemingly with the UnityPlayer.dll file and therefore no change was necessary on that front.

Thank you kindly, and have a happy spooky month!
