If the Tokyo Game Show trailer was any indication, flOw developer Thatgamecompany is not shying away from abstract projects. Speaking at the Montreal International Games Summit (via Gamasutra), TGC President Kellee Santiago explained how music played an important role in the the initial development phases of Flower. Two musical pieces were commissioned to set the tone of the project, according to Santiago, to "get everyone on the same page... doing sample audio tracks to evoke the emotion [will] keep everyone's work consistent."
Details about Flower itself are rather scant, aside from confirmation that at least part of the game has to do with growing flowers. Said Santiago, Flower involves the "possible emotional impacts of the feeling of growing a flower, and possible interactions as the sun." The title is due out on the PlayStation Network sometime in 2008.
