Penumbra Sales Figures?

[Lockheed]

To the developers:

I don't know if this is the type of thing you would be willing to share, but if so, after a certain amount of time has passed it would be interesting to know how the sales have been for the game, since it is effectively an indie project and (relatively) small, and seems to have gotten a fair bit of its publicity from word of mouth from fans. My hope is that we will see it compare well with sales figures for other games, though of course taking into account the different development model from big game houses.
