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.
Dropbox (250MB Extra space)
Penzu (20% off yearly subscription)
Hole in the Wall Hosting ($10US per year for 300mb space, 30gb bandwidth)

I keep it, and will continue to do so as it provides an easy mechanism I can use to contact people who I would have otherwise lost contact with. This deleting facebook meme has become a pain as it means I have lost contact with a couple people I don't have any other means to contact. I have mostly found them through friends of friends ect.
