Not to be confused with the excellent SSH client, PuTTY, PUTTY (http://www.cokeandcode.com/demos/putty3/putty.html) is a cool puzzle game I found on the Internets. I'm on level 6 as of posting this, and am enjoying myself greatly. :)
Edit: Done. :)
Oh, and if you guys manage to beat those levels, I made one of my own. It's pretty easy, but yeah. :)

Place it in your user directory in the folder named ".putty" and open in the game via the level editor. :)
Example:
Windows: C:\Documents and Settings\user\.putty\
Linux: /home/ian/.putty/
