concept of "game spaces" and approach to story-relevant choices, including the social feature that allows online players to learn about others' decisions. The level demonstrated was an area of Europolis corresponding to modern-day Prague. By late September 2013, RTG completed the vertical slice of the game, implementing all of its core features in a 20–30 minute-long demo, which was shown to the public at Journeycon, a fan convention taking place in Oslo on 23 November 2013. The demo covered a single level, Friar's Keep, and Kian Alvane's escape from it. Also at Journeycon, Red Thread Games announced that the game's soundtrack is composed by Simon Poole, the lead sound designer of Dreamfall. The pre-alpha milestone was reached on 6 December 2013, with the alpha and beta stages planned for spring and late summer 2014, respectively. In March 2014 (at the Game Developers Conference and the EGX Rezzed expo), RTG revealed a new level from the alpha version, showing Zoë Castillo in Storytime at the very start of the game. Work on the beta version began in May 2014, and the first "book" (prologue, two chapters, and an interlude) was feature complete by mid-June. After returning to an episodic video game format in June 2014, Red Thread Games released Book One, Reborn, as the first episode of Chapters on 21 October 2014. On 26 August 2014, RTG announced a musical competition among Kickstarter backers and other fans, who were asked to submit soundtrack pieces to be included in the finished game. This announcement sparked a controversy regarding "exploiting unpaid [fan] labor", and the contest was canceled the next day by the developers. The development of Book Two, Rebels, took longer than Red Thread Games had anticipated. Its initial release date was projected to 24 February 2015, but due to its larger scope, technical challenges associated with creating a framework for an episodic game, and the prolonged testing cycle necessary for the choice-and-consequence subsystem, it was delayed until 10 March, and then again until March 12, when critical bugs were discovered and required another day of testing. Although no major changes were made to the core plot of the game since its conception, player feedback to Book One "factored into" the near-complete rewrite of Book Two dialogue. Despite the extended testing of Book Two, its first released version contained a bug that corrupted several choice-and-consequence flags, which had a negative impact on
