Thanks for the indepth description of duality. It was interesting to read and you're absolutely right; duality doesn't necessarily mean binary or opposites, it can also mean parallel and everything in between. I picked this theme exactly for the reason that it's open for a wide range of interpretations without limiting or restricting the developer too much. Frankly the biggest reason and intended effect of the theme was the fact that because the existence of a theme was announced early people are immediately discouraged from starting to work on something specific prior to the jam period.
Sorry to hear about your illness and other struggles. I'm right there with you but with opposite result I suppose. I am unable to commit myself to longer projects and jams so these short ones are perfect for me. I've even done a 3 hour jam a couple times :D
