Speaking to Joystiq, Bruce explained the motivations behind the midstream re-christening, by way of explaining the evolution of the name and the game. "Hazard' was chosen back when I was first exploring the geometry system," he said, "and the game was all about killing players in an arena combat game, but eventually that idea died off, and I just kept calling anything related to the geometry system 'Hazard' because I was used to it." He began adding "philosophical" themes "about choices and metaphor" in 2009, at which point the "Journey of Life" subtitle came in.
Now, he explained, the game is less about philosophy and more about "non-Euclidean space, non-physical geometry and massively toying with expectations in a meaningful way." Antichamber covers those angles better than Hazard did. "The game speaks for itself, so the name change is really just bringing it up to date with everything else that has changed."
