The "unstability" property can be added to any existing game, with the single pass of a vertex shader ;)<p>Some themes simply lend themselves to engendering more "creativity" than others. I knew it was going to be "unstable", because it's universally hated / feared. But was chagrined to see "One tool, Many uses". It's really the ideal theme for a game jam with time constraint. The inspiration just flows. And really the themes are vague enough to get away with anything.
