All of my games are available to everyone for free.
However, if you enjoyed any of my games, a couple of bucks to cover website hosting costs and support my ongoing efforts would be gratefully appreciated. I think $2 per game enjoyed is a fair price. Thanks.

Well, I've only played two of these, though I own two of them.
Suffice to say: Mirror's Edge - Woohoo! One of my favourite games of 2009.
And I have a copy of Oni. Will play it... one day.
