Paper Cakes is unique at the IGF because it’s a novel game that would have worked just as well on paper as it does on a computer. In fact, if the game is ever published outside the freeware universe, I think a paper-bound walkthrough is called for with dotted “fold here” lines to explain each level. I didn’t pester developer Machiel van Hooren about that specific idea, but I did ask him about the paper prototyping process, simulating a sheet of paper on a tablet, and the game’s future. Read on for his answers.
