| SRC-0001 | Lobotomy Corporation | Monster Management Rogue-Lite | S0 | Project Moon | Lobotomy Corporation is a rogue-lite monster management simulation game developed and published by Project Moon, released on Steam on April 9, 2018. The player takes the role of a facility Manager tasked with extracting an energy substance called Enkephalin from creatures known as Abnormalities, which range from harmless to extraordinarily dangerous. Drawing heavy inspiration from the SCP Foundation collaborative fiction universe, the game casts the player as a manager of an underground containment facility housing a menagerie of supernatural creatures. The core loop involves sending employees to interact with Abnormalities to produce Enkephalin while managing the safety and sanity of the staff. The game features an AI assistant named Angela who guides the player, and a cast of Sephirot—robot overseers representing different departments of the company—each with their own narrative arc through the game’s deep and frequently tragic story.

| SRC-0002 | Library Of Ruina | S0 | Project Moon | Library of Ruina is a deck-building RPG developed and published by Project Moon, released in full on Steam on August 10, 2021 after an Early Access period. It is a direct sequel to Lobotomy Corporation, continuing the story of the world known as the City. The game is set in the Library, where the protagonist Angela and her librarian Roland guide visitors—known as guests—through a series of battles structured as receptions. The Library sends out Invitations to lure guests inside, where they must face the librarians in card-based combat. The game uses a deck-building system where players construct decks of combat pages and equip key pages that determine character stats and passive abilities. During receptions, the librarians clash with guests’ dice rolls, with higher values winning and dealing damage. The narrative explores the consequences of the events of the first game, the Distortion phenomenon sweeping the City, and Angela’s quest to create one perfect book that will complete the Library.

| SRC-0003 | Limbus Company | S0 | Project Moon | Limbus Company is a turn-based gacha RPG developed and published by Project Moon, released worldwide on February 26, 2023 on Steam and mobile platforms (iOS and Android). It is set in the same universe as Lobotomy Corporation and Library of Ruina, in a dystopian megacity known as the City.

Each Sinner is based on a character from classic literature, and their personal stories unfold across chapters called Cantos. The game builds on the lore established in the previous two games and introduces the Distortion Detective narrative thread, where the Limbus Company bus (Mephistopheles) travels across the City’s Districts.

It notes that the game was developed by the South Korean independent studio Project Moon, founded and led by Kim Jihoon.

| SRC-0005 | Library of Ruina - Wikipedia | S2 | Wikimedia Foundation | The Wikipedia article for Library of Ruina describes it as a deck-building turn-based RPG serving as a direct sequel to Lobotomy Corporation. The story continues in the City, a dystopian megacity governed by a mysterious entity called the Head and divided into 26 districts each run by a Wing mega-corporation. The City is populated by Fixers—mercenary agents who undertake jobs ranging from combat missions to courier work. The narrative picks up after the events of Lobotomy Corporation, where the AI Angela creates the Library from the Light emitted at the end of the first game and recruits Roland, a low-level Fixer with a hidden past, as her first librarian. Guests are lured to the Library via Invitations; defeating them in battle transforms them into books, fueling Angela’s goal to craft one perfect book. The article covers the Distortion phenomenon—people transformed into monstrous beings after the Light’s release—and the Reverberation Ensemble, an antagonist faction led by Argalia, known as the Blue Reverberation. Achieving Floor Realizations across all nine floors is required for the true ending, which results in the Library being expelled to the Outskirts, the desolate wasteland beyond the City’s borders.

| SRC-0006 | Limbus Company - Wikipedia | S2 | Wikimedia Foundation | The Wikipedia article for Limbus Company documents the game as a turn-based gacha RPG developed by the South Korean studio Project Moon and released worldwide on February 26, 2023. It is the third major installment in the Project Moon shared universe, following Lobotomy Corporation and Library of Ruina, and takes place in the same dystopian City.

Each of the twelve Sinners is explicitly based on a character or author from classic world literature: Yi Sang (Korean poet Kim Hae-gyeong), Faust (Goethe’s Faust), Don Quixote (Cervantes), Ryoshu (Akutagawa’s Hell Screen), Meursault (Camus’ The Stranger), Hong Lu (Cao Xueqin’s Dream of the Red Chamber), Heathcliff (Brontë’s Wuthering Heights), Ishmael (Melville’s Moby-Dick), Rodion (Dostoevsky’s Crime and Punishment), Dante the manager (Dante Alighieri’s Divine Comedy), Emil Sinclair (Hesse’s Demian), Outis (Homer’s Odyssey), and Gregor (Kafka’s The Metamorphosis). Their personal guide Vergilius is named after Virgil from the Divine Comedy. The Distortion phenomenon, introduced in Library of Ruina, continues to affect the City’s population. The game features an original soundtrack composed primarily by the Japanese indie band Mili in collaboration with Studio EIM, continuing the musical partnership established in Library of Ruina.

| SRC-0009 | GameSpark Interview with Kim Jihoon (April 2018) | S1 | GameSpark (IID, Inc.) | A press interview conducted by Japanese gaming outlet GameSpark with Project Moon director Kim Jihoon in April 2018, coinciding with the official Steam release of Lobotomy Corporation. In the interview, Kim discussed the game’s development history, revealing that the project began life as a college club activity in January 2015. The initial concept was to create an SCP Foundation-inspired monster management simulation game—something Kim felt was underserved in the gaming market. At the start, Kim was the primary developer with a team of just four people, expanded to ten by the time of release. The interview covers the design philosophy behind the Abnormalities, the Enkephalin extraction mechanic, and the game’s difficulty and deliberate opacity, which Kim acknowledged was intentionally punishing. This interview is one of the earliest and most cited sources for understanding Project Moon’s origins as a small independent Korean studio that grew entirely out of Kim’s student passion project.

| SRC-0010 | PC Gamer - Limbus Company Coverage | S2 | Future plc | Coverage of Limbus Company by PC Gamer, one of the most prominent English-language gaming publications, which characterized the game as a “gory road-trip through one of indie gaming’s darkest worlds.” The article highlighted Project Moon’s status as one of South Korea’s best-known independent game studios and documented the growing Western recognition of the studio’s body of work following the cult success of Lobotomy Corporation and Library of Ruina. The coverage situates Limbus Company within the tradition of dark, narratively ambitious indie titles and notes the game’s successful free-to-play model and its accessibility to newcomers despite its deep connection to the previous two games.

| SRC-0011 | Rock Paper Shotgun - Lobotomy Corporation Review (April 2018) | S2 | Gamer Network | A review of Lobotomy Corporation published by Rock Paper Shotgun in April 2018, contemporaneously with the game’s full Steam release. The review is notable for its ambivalent tone: the reviewer praised the game’s atmosphere, creature design, and quiet ambient horror but criticized its user interface and gameplay as “unnecessarily complicated.” More importantly for historical record, the review documented significant issues with the initial English-language translation that plagued the game at launch. The localization was described as poor, with grammatical errors and unclear instructions that compounded the game’s already steep difficulty curve. This is a well-known piece of Project Moon community history, as the translation has since been substantially overhauled and improved. The review serves as a valuable contemporary source for understanding both the critical reception of the game at launch and the technical hurdles Project Moon faced in bringing a Korean indie game to the global market.
