Rob and Shireen are both big Peggle fans. During the development of Peggle 2, Rob wrote in to PopCap for a little help with proposing to his girlfriend – and the studio obliged.
PopCap came up with a special testing day scenario: Rob would tell Shireen he wrote this essay into PopCap telling them how she's their biggest fan and the company would fly the two out to San Francisco to test an early build of the game and provide feedback. The early build, comprised of five levels, would culminate in a final level where Rob would ask Shireen to marry him.
Now, we don't want to ruin the ending for you, but maybe grab a tissue before you hit the play button above, okay?
