Kellee Santiago, co-founder of thatgamecompany, left the Journey developer today. "Thanks so much for the kind words today, I feel so much love and gratitude," she Tweeted. "It's time to hit the 'Start New Journey' button!" She has yet to announce her destination.

Santiago told Gamasutra that she hopes to take what she's learned from making thatgamecompany's three PSN games, "and go forth and take it into new arenas." She said she saw her role at thatgamecompany as supporting Jenova Chen's visions for game design. "... I felt like I have done everything I needed to do there, and that he's in a great place now to go on and continue with some of the other people at Thatgamecompany, to take that to a whole new height." Gama also cites anonymous sources who warn of other "key staff departures."

A thatgamecompany representative told Joystiq "Obviously, Kellee has been a huge part of thatgamecompany over the past six years. Even though it's sad to see her leave, we are very excited to see what she does in the future."
