[Update] Valve has added a Steam page for Chime, revealing it will launch on September 6.
[Original] Non-profit publisher OneBigGame has revealed plans to release its charity-focused puzzle title Chime on the PC in an exclusive edition at the "end of the summer." [See update above]Chime for PC will feature all the tracks from the original release along with Portal's now infamous end credit track, "Still Alive."
Originally released for the Xbox Live Arcade, Chime was developed with charity in mind as a portion of the game's profits have been donated to OneBigGame partners Starlight Children's Foundation and Save the Children. With word of a PC version, developer Zoë Mode has revealed Chime for PC will also see a portion of its profits donated to OneBigGame in order to benefit its numerous charity partners.
Although no price point was revealed for the PC version, we presume it will carry a price similar to the XBLA price-tag, which launched at $5 in February 2010.
