While I do have, ahem, "plans" for dabbling deeper in the world of non-text-based video games, thus far I've only had a hand in the making of three, in the capacity of lead writer and lead playtester. All three of these games were made with the talented Instanbul-based game developer Tonguc Bodur.
It's only the earliest of these three games, Bottle: Pilgrim, that I feel any great sense of semi-ownership towards, as the story was based on my own original idea...which thereby held significant sway over the imagery and mechanics within the game. Observe the beautiful "beach at dusk" screenshot on this page: still one of the most iconic images Mr Bodur has produced during his twenty-plus game run. The other two games, by contrast, were based more on Tonguc's ideas and early scribblings, reducing my role to a kind of "script doctor" and "lead adviser".
I'm certainly proud of my contribution to all three of these narrative-based "walking simulators", even if there's a certain regret attached to the voice-acting I did for the initially-released version of Bottle: Pilgrim (rushing things never produces ideal results, kids)! But if you're willing to be forgiving, I'm happy to provide the Steam Store links to all of the games, which should be enjoyable by the standards of anyone who believes that video games can be about more than simply shooting shit and/or leaping heroically from platform to platform:
