the player would have to work out how the rules work, and expanded the game in that direction. Bruce said in a 2011 interview with Kotaku that "the game started off as being all about geometry... I needed to find a way to represent that [non-physical geometry] to players... so I needed to work out why we would need this non-physical geometry in the world and it took me a couple years but after combining geometry and space and perception, I realised that the real reason that this game is interesting and is working is because it's about psychology." As he worked out puzzles, he found that injecting philosophical ideas helped to lead to puzzle designs or otherwise augment established puzzles, and made that part of Antichamber'''s approach. The game's simple art style was partially to distinguish the game from other Unreal Engine games, while also to aid in masking the work behind the inverse lighting system used in the game. On April 2, 2012, Antichamber became the seventh game to receive funding from the Indie Fund with Bruce citing the award as "finishing funds" to ensure the game can be released in 2012, and was ultimately released in January 2013. Music The soundtrack for Antichamber consists of ambient music composed by Siddhartha Barnhoorn. The music evolves over the course of the game, starting with nothing more than one ambient layer in the first level and gradually progressing into a complex soundscape. In an interview with IndieGames.com, Barnhoorn revealed that the soundtrack comprises sounds from various guitars, the shakuhachi, the koto, and synth pads. In addition, Barnhoorn stated that the non-synth sounds are digitally manipulated "here and there in order to make the sounds a bit longer than they would appear naturally". Antichamber Suite, a track consisting of music from the game, was released via Bandcamp on February 13, 2012. The track was also featured in the Nubuwo Debut Bundle released March 2, 2012. The full soundtrack was released on February 18, 2013. Reception Pre-release The PC version was well received by critics prior to its commercial release. In 2009 the game was featured in the showcase at the Tokyo Game Show Sense of Wonder Night, and was a finalist in the Independent Games Festival China. In 2010, indiePub Games's third Independent Game Developers' Competition awarded the PC version the prize for Technical Excellence. In 2011 the game was a
