We're still tweaking a lot of major aspects of the plot, levels, and mechanics. Isaac is doing a re-write of the code which is briefly setting us back but should save us a lot of time in the long-run. We recently had a long discussion about adding jumping to the game. In the end, I think we came up with a great compromise that will add a lot to the game while maintaining a uniquely robotic feel.
David was wondering what the mood of the game would be as it progresses so I did some small color studies of some of the areas that I've got firmly envisioned.
