Sky: Children of the Light, thatgamecompany's follow-up to Journey, released three years ago for iOS devices before making its way to other platforms and the developer is celebrating by holding the biggest event the game has ever experienced. There are special birthday themed events, new areas to explore, performances from the thatgamecompany band, and more.

To mark the occasion, we spoke with Jenova Chen, thatgamecompany's co-founder and the director of Flow and Flower, as well as Journey and Sky: Children of the Light. We talked with Chen about potential regrets in launching exclusively on iOS, whether the game will make its way to more platforms, why Twitch is crucial to the success of modern games, and the potential of future collaborations, like the one it recently did with The Little Prince, based on the classic children's book and the 2015 film adaptation.

Is this the biggest event that Sky has put together?
