We last caught designer Tyler Glaiel at PAX, where he showed a four month build of Closure along with artist Jon Schubbe. It’s a puzzle platformer of light and dark, where the parts of the world wink in and out of existence along with the light that illuminates them.

Tyler and Jon are the same compact speakers as they were at PAX, which allowed us to hit on diverse topics like the updated build, their new music designer, and their inspiration for polishing the game.

Tyler Glaiel is programmer and game designer for Closure, but he looks more like a PAX attendee than an exhibitor. It shouldn’t come as a surprise that he made the PAX 10 though. At nineteen years of age, he’s already spent eight years developing Flash games, and five years working with Closure‘s artist, John Schubbe. Check out the full text of the interview for what’s new in Closure, a look at Tyler’s design process, and even a little bit about why platformers have been so cool lately.
