"Doing something new can be a really big risk and adding something innovative to something already exists can often disrupt and create new games," she said. Swift told the crowd that she and the team approached Portal problems as small gamelets in isolated environments. To her, trying to innovate too much at one time can lead to failure. Jurassic Park: Tresspasser, she quipped, is an example of a title that "tries a lot, and fails at all." Swift's mantra is to try one thing and polish it to the best of your ability.
Following her talk, Swift started a video of one level of portal to explain the depth of the puzzle. In Portal, you can make a blue and orange-rimmed portal that interact with one another. You can attach a portal to most surfaces, although reflective and glass surfaces will not take a portal, "just to make your life more difficult," Swift notes.
