When the game ends you get your highscore and a verification code (click the screen to copy). This code you can post in any forum or send it to your friends to show them your score.

To check if a highscore is valid copy the code and run Xen.exe - a message box will ask you wheter to check the code or not. If Xen is already running you can press the V key (the game pauses) and enter the verification code directly.
