Interactive
I wrote an interactive piece of writing, using a software called Twine. These things are generally called "Interactive Fictions". There's no gameplay element to it, you navigate it by choosing from a selection of possible responses.
Have a crack at it if you're in the mood to read. It's called Conversation.
I have also made some more straightforward (but not very straightforward) games.
Here they are:
Body Mutilation. Made during the Global Game Jam.
I Am Become Consciousness, Collapser of Waves. And this one was made as a group, also during the Global Game Jam.
