Development
The game's development took ten years, and it was released on Steam on 28 December 2023. The first commits were registered on GitHub as early as 2013, with game becoming playable around 2017. A rectangle packing library, called rectpack2D and created specifically for Hypersomnia, was used in the game Assassin's Creed Valhalla, by American drone manufacturer Skydio, and inside the Snapchat's Android mobile app. The ACM Transactions on Graphics journal has also published a paper referring to rectpack2D in 2019. A 2018 patent, belonging to Unity referred to the assemblage buckets problem which was conceptualised by Czachurski a few years earlier on one of Stack-Exchange-owned forums. Although Hypersomnia 's lead developer claimed that no game engine was used in the development process, he confirmed to the technology news website "Kontrabanda" that "a few" external programming libraries were used.
