Question: How many employees did Blitz Games have the year that Bithell joined Bossa Studios? Passage 1:Bithell independently developed an early version of the Thomas Was Alone video game in 2010 while working for Blitz Games, where he was a junior designer, and later a level designer on games such as Tak and the Guardians of Gross, , iCarly (video_game) and , from 2007 to 2011. He developed the prototype game in 24 hours and released it for free online through the Kongregate website, receiving 100,000 'plays' in the first week. He joined Bossa Studios in February 2011, working to expand the flash-based Thomas to a full title and learning how to use the Unity engine in his time there. The full game was released on 30 June 2012 and went on to sell over a million copies, winning a BAFTA at the 9th British Academy Games Awards in the "Best Performer" category (for narrator Danny Wallace) and receiving a further two nominations ("Best Original Music" and "Best Story"). He left Bossa in January 2013 to "concentrate on indie development". He since worked on a Robin Hood-based stealth game named Volume, which was released on 18 August 2015 for Windows, OS X, and PlayStation 4 and Vita platforms. In 2016, Bithell released EarthShape, a virtual reality game for Google Daydream. Bithell collaborated with composer Russell Shaw and animator Tim Borelli on the project. The game featured voice acting from British comedian Sue Perkins. In August 2017, Bithell released a new game Subsurface Circular, a first of what he calls "Bithell Shorts" that are designed as short, focused narrative games. In May 2018, Bithell released another short titled Quarantine Circular.

 Passage 3:Nazism found an audience in the country, with pro-Nazi elements organised by Louis Weichardt in 1932 under the name South African Gentile National Socialist Movement, a group that soon became known as the Greyshirts. Although the group enjoyed some support and continued after the Second World War they never became sufficiently important for the government to take action against them. The other main fascist group was the Ossewabrandwag (OB), founded in 1939, a group also inspired by Adolf Hitler. The two differed however as the Greyshirts emphasised Aryan race rhetoric and so organised amongst the various white immigrant communities whilst the OB were specifically for Afrikaner only. A third, more minor group, the New Order, emerged in 1940 under the leadership of former cabinet minister Oswald Pirow. After the Second World War Pirow became an important figure in neo-fascism, working closely with Oswald Mosley, Nation Europa and A. F. X. Baron. Nazi Germany sought to encourage such activity with former Olympic boxer Robey Leibbrandt active as an agent for the Abwehr during the war. The Nazi Party itself also organised until it was outlawed in 1936.
