After we published our first game, I responded to its weaknesses in a very reactionary way. The game had a good sense of beauty, theme and tone but it was weak in mechanics and design. Because of this I shied away from making anything remotely attractive for quite some time. Furthermore, I would not "indulge" myself in any sort of world building, aesthetics or story. Everything I made was spartan, abstract and ugly. Most of them played pretty well, but it did feel at times that I was designing uphill.
Almost a year later, and I am recovering. I am making beautiful things again and it feels good. It's easier to work on something pretty, it inspires me. It was important for me to go through this restriction, and I think it has made me a better designer, but I am glad to be back.
