Red Square is, to say the least, tricky. I think it's entirely safe to say that the majority of people do not survive for more than twelve seconds. Many people don't even survive two seconds.
Now, even though it should be pretty obvious, I'm going to clarify that I'm not talking about a prominent location in Moscow. I was not going to bother saying that but I am not a hamster, I know there's people that will see "Red Square" and decide that it is that location in Moscow and just stop thinking. (sad but true)
When you click on the red square the four blue rectangles begin to move. Your mission, should you decide to accept it, is to move the red square so that it avoids all contact with the blue rectangles. You must also avoid contact with the edge of the playing field.
The first time I played it I lasted 1.23 seconds. With practice I have achieved a personal high score of 9.58 seconds and trust me when I say that in this game, that's a long time.
