Project Moon Life

Project Moon Life is an unofficial browser-based urban life simulator inspired by Lobotomy Corporation and Limbus Company. The free seeded simulator lets players explore life in the Nest, Backstreets, or Outskirts through choices that shape attributes, careers, relationships, and endings. A $10 USD one-time AI Chapter Pass unlocks unlimited AI lives across the AI Chapter and Participating Life modes, with cloud saves, recurring characters, and lasting consequences. The site also offers a life archive, field guide, downloadable backups, and sample share cards.

Project Moon Life is a browser-based urban life simulation game that lets players create a fictional resident and guide that character through a changing city. The experience revolves around personal decisions, career development, relationships, unexpected events, and the consequences of choices over time. Rather than focusing on a single objective or a fixed storyline, the game creates a simulated life in which circumstances and decisions influence the character’s experiences and final life record.

Players begin by creating a resident or accepting a randomly generated starting situation. The character may come from different neighborhoods, including a Nest, the Backstreets, or the Outskirts. The starting location, family circumstances, and other background details are influenced by a life seed. These starting conditions establish the context for the simulation, but they do not determine the entire outcome. Players shape what happens next through their decisions and the opportunities they pursue.

The game tracks five primary attributes: health, sanity, resources, connections, and reputation. These fictional measurements change as the resident experiences events and makes decisions. For example, accepting a demanding career opportunity may improve professional prospects while placing pressure on health or other attributes. Helping another character may strengthen a relationship while consuming resources. These trade-offs give the simulation its central challenge: choices can provide benefits in one area while creating difficulties elsewhere.

Project Moon Life uses a time-based simulation system organized around four seasons. At normal speed, one simulated year takes approximately one minute, although players can pause the simulation or accelerate time up to 32 times its normal rate. Important decisions can pause the clock, giving players an opportunity to consider their available options. The pace makes it possible to follow a character’s development across many years without requiring every event to be played in real time.

Career development is another part of the experience. Residents can encounter professional assignments, pursue career paths, and discover special routes through the city. The available opportunities depend on the game’s rules, the character’s circumstances, and previous choices. The simulation records important events and developments, allowing players to review the resident’s history and see how their decisions influenced the life that unfolded.

One of Project Moon Life’s main advantages is its free simulator. The base experience uses a seeded rules engine and built-in events rather than requiring an AI model to generate every part of the story. Players can start unlimited lives without creating an account or making a payment. The simulator includes its built-in events, career paths, time controls, replay functionality, and local life archive. This gives users a way to explore the game’s systems before deciding whether they want the additional AI-guided experience.

The seed system supports repeatable simulations. A seed establishes the character’s starting circumstances, and using the same rules version, seed, and sequence of choices reproduces the same simulation results. Players can therefore revisit a beginning and make different decisions to explore alternative outcomes. This feature makes the game suitable for people who enjoy experimenting with choices and comparing how different approaches influence a fictional character’s life.

Project Moon Life also provides two optional AI-guided modes: AI Chapter and Participating Life. Both require an account and use cloud-based saves. AI Chapter creates narrative scenes that respond to the resident’s recorded history, relationships, and earlier promises. The story is divided into chapters, with up to 24 major decisions across the guided experience. Instead of producing an entirely disconnected story each time, the AI-generated scenes are intended to reflect the character’s previous experiences while the game rules determine the effects of confirmed choices.

Participating Life provides a more flexible way to influence the simulation. Players can choose from the available actions or propose a possible next step using their own words. The AI interprets the proposal and maps it to an action supported by the game. Before the proposed action changes the character’s life, the player can review and confirm it. This creates a balance between natural-language input and a structured simulation system, while keeping the player involved in important decisions.

The distinction between the AI-generated narrative and the game’s underlying rules is important. AI can provide additional story details and interpret proposed actions, but the simulation engine determines the actual attribute changes, risks, and recorded outcomes. This approach helps keep narrative passages connected to the resident’s established history and the actions that were confirmed. It also means that Project Moon Life is better understood as a guided life simulation with optional AI assistance than as a completely unrestricted chatbot game.

Saving and replaying lives are additional features. Free simulator records are saved locally in the current browser, rather than automatically syncing to an online account. Players can export a JSON backup to preserve a life or move it to another browser or device. A loaded free simulation can continue offline, but players should export important records before clearing browser data or changing devices. AI-mode records use cloud saves and require an internet connection to continue.

The game also provides ways to review and share life outcomes. Its records can include a character’s origin, career, achievements, attributes, relationships, and significant choices. Players can use seeds to share a starting point with others and explore different paths from the same circumstances. Shared starting points do not automatically transfer another player’s complete story or decisions.

Project Moon Life is an unofficial fan work inspired by the fictional settings of Lobotomy Corporation and Limbus Company. It is not affiliated with, endorsed by, or produced by Project Moon. The website describes its artwork and event writing as original. The game is intended for players aged 15 and older and includes fictional themes such as death, illness, crime, and psychological distress, so users should consider the content information before playing.

The optional AI modes also have privacy considerations. AI lives are stored in the cloud, and text entered into Participating Life is sent for interpretation. Players should use fictional information rather than private real-world details. The free simulator’s local saves and the AI modes’ cloud records operate differently, so understanding the distinction is useful when choosing how to play.

Project Moon Life is best suited to players who enjoy narrative simulations, role-playing decisions, career progression, and exploring how choices affect a character over time. Its unlimited free simulator provides substantial access without a subscription, while the optional AI modes add more personalized scenes and natural-language proposals through a one-time payment. Its main limitations are the browser-based save system, the need for an account and internet access for AI modes, and the fact that the experience follows structured simulation rules rather than offering unrestricted control over every event.

Pricing

Project Moon Life uses a freemium model with a separate one-time payment for its optional AI modes.

• Free Simulator: $0. Unlimited simulated lives with no sign-in or payment required. Includes built-in events, careers, time controls, replay functionality, and local browser saves.
• AI Pass: $10 one time. Unlocks both AI Chapter and Participating Life, with unlimited AI life starts while the service operates.
• Subscription: No recurring subscription is listed for the AI pass.
• Additional costs: The website does not list a separate recurring fee for the two AI modes after the pass is purchased. Temporary usage and concurrency controls may still apply.

Prices are in US dollars and may change. The AI pass requires an account, while the free simulator remains available separately.

Review

Project Moon Life offers an engaging approach to life simulation by combining character development, career choices, relationships, and long-term consequences in a browser-based game. Its seeded simulator makes repeated playthroughs useful for exploring different outcomes, while the five tracked attributes give decisions a clear connection to the character’s changing circumstances.

The free version is a significant strength because it allows unlimited lives without registration or payment. Local saves and JSON exports also provide a practical way to preserve and move simulation records. The optional AI modes add more narrative flexibility: AI Chapter generates scenes based on a character’s history, while Participating Life allows players to propose actions in their own words and confirm them before they take effect.

The main drawbacks are the separation between local and cloud saves, the need for an account and internet connection for AI modes, and the structured nature of the available actions. Players seeking completely unrestricted storytelling may find the game more guided than an open-ended AI role-playing experience. Its fictional content warnings should also be considered before playing.

Project Moon Life is worth considering for fans of narrative-driven life simulations who want to explore how decisions shape a character’s history. The free simulator is a useful starting point, while the one-time AI pass offers additional storytelling and player participation without a recurring subscription.
