Hi, thanks for writing a comment, I don't understand where you could see such a game? I am the only developer of this game, and it saddens me that someone has overloaded my game. You can watch this video, there you can see where the third key is, thank you for playing!
Thank you for showing where the third key is located at.
About someone else overloading your own game, it feels sad I know! This often happens here, I have seen it couple of times during the years I spent here! Take it as a good sign as this means your game is too good, to the point others are taking it because of how good it is.
