I never did write a follow up post about the result of releasing the demo.

The reason is that I'm not really sure what effect it had after all. It certainly didn't reignite sales of the full version - shortly after the demo came out, sales dropped right down to a trickle. On the other hand, I'm not convinced that the demo is to blame - downloads of the free version are also pretty dismal, so I don't think people are getting that instead of the full version.

Sales were heading down anyway when I put the demo out (that's partly why I did it), and I think that as it dropped out of the charts, that accelerated its decline.

It's all just conjecture - I have no traffic stats from the App Store, so I'm just left guessing at what causes the effects I see.

I'm pretty happy with how the game did overall - featuring on the front page did it a world of good - but it would be good if I can stretch its tail out a bit longer.

A few more articles like this: http://www.msnbc.msn.com/id/30508084 would do nicely.
