I was approached by Iron Galaxy to create 20 levels for the popular game Scribblenauts: Remix. The deadlines were tight, with 4 weeks to learn the largely undocumented proprietary editor, build and program 20 levels, then send them to Warner Bros for feedback / testing and fix any issues. I hadn't much time for dilly-dallying. To make it happen, I created a plan that involved only making a few of the easier looking levels the first week while I learned the tools. Then I ramped up development to the point where I had to build multiple levels per day to meet the quota. One level would be building and deploying to a device, while another was in level design, and yet another needed to be scripted. Context switching so frequently meant I needed to standardize a system to help me keep track of what I was working on (editor's note: I don't recommend context switching so frequently, but I needed to be iterating on multiple things at a time to get the job done). I used a whiteboard to keep track of the immediate tasks on my plate. There was always a new problem to solve and a new thing to check off my whiteboard.
At the end of the month, I had accomplished the task, with some time on my contract left over. I was able to use that time to write 40 pages of documentation for the editor so the next person didn't have to go in as blindly as I did, plus I got to work on a couple other things Iron Galaxy was working on at the time. Overall, it was very challenging and also very fun.
