Portal speedrunning has been around for a long, long time, so we had some of the developers from Valve Software watch one of the speedruns on our show Devs React to Speedruns. Not surprisingly, they ended the video with way more questions than answers about what exactly speedrunner CantEven was doing to make his playthroughs so quick. So, we had CantEven join the call to answer any and all questions the Valve team had about the secrets of speedrunning Portal.
Participating in the interview from Valve are: Erik Wolpaw (writer), Jeep Barnett (programmer), and Garret Rickey (programmer).
