As Valve themselves once said, making games is hard. Over the course of a weekend with the Portal 2 Perpetual Testing Initiative DLC, I've established my own version of that rule: making games is harder when you're an idiot.
I recorded my first baby steps with the new test chamber editor, and in doing so have created a permanent record of my failures as a human being. Marvel as I crush myself with a lift! Yell at your monitor as I fail to consider an array of incredibly trivial solutions to my own puzzle!
By way of compensation, I spent another couple of hours working on my test chamber and eventually hammered it into something resembling an actual level. You'll be able to download the final result - the PCG Reflection Challenge - from the Portal 2 Workshop when the DLC launches later today. 'Reflection' means two things, in this context. One: what you do with a laser. Two: that I need to have a bit of a think about my life.
