Gamertell has posted an interview with Mark Darin, one of the graphic designers for the new game, Strong Bad's Cool Game for Attractive People.
From the interview:
"Darin assured the players that, like the Homestar Runner cartoons, this game will also be full of easter eggs and other hidden surprises. 'When you beat the episode, you can continue to play and find all of the hidden stuff in the game, you can also look for it during game play.'
Darin went on to explain that the player controls the tone of any conversation. You can choose to compliment characters or insult them, which of course will effect that characters reaction. He also indicated there will only be one ending for the game, so you are free to play as you want without worry of affecting the outcome."
