At first I thought you meant people had been stealing your game, which wouldn't be so good, but since they're just linking back to the download page on TDC, I think it's great.
Congratulations on making a game good enough that people outside of the klik community want to play it.
It is always a nice feeling when other people notice your work. Then you gradually start to get more well known. GameTrailers took notice of Mr Stump's Dentures 2, for example, and that is probably my greatest achievement at getting the name known
