Colin Northway's Fantastic Contraption (browser edition, 2008ish) is the first game I ever worked on. It eventually (and directly) led to the formation of Radial Games, so the game means a heck of a lot to me!
In the original edition, I rarely touched the code, but did do some level design, a ton of community management, and a smidgen of bizdev work.
In 2016, we "got the band back together" to make the VR edition of the game. Full circle! Fantastic Contraption is the first commercial VR title I helped create (together with the rest of Radial Games, Northway Games, and A Shell In The Pit).
I've got a lot more to say about it. Might update this page in the future. For now, here's some more reading:
