I have two games so far that have demos available.  Scara is my VB.Net RPG, and Blink is my C# platform game using XNA.  Check out the links on the left for more info.

A third project is in development:Volk.  It's a single-player MUD console app.  For the young'uns, a MUD is like a text-only MMORPG that was popular mostly in the 90's.  It has a much-faster development cycle and in the course of one week I have completed a map, combat basics, stores, classes, a few creatures, and even aliases.
