Currently, i'm in very bad position because your game has locked my mouse and stopped working "CTRL+ALT+SUPPR" security command.

It's security failure. Check your code guy !

Yes the game lock the mouse in the middle of the screen when you play, but you can press ESC to pause the game and unlock the mouse.

I have no problems with "CTRL+ALT+SUPPR".

Which file did you download (64-bit or 32-bit) ?

And what is your OS (Windows 7, 8, 10...) ?
