Project Moon Life

What is Project Moon Life?

Project Moon Life is a browser-based urban life simulation set in a City inspired by the worlds of Lobotomy Corporation and Limbus Company. A resident begins in a Nest, the Backstreets, or the Outskirts, then moves through education, work, relationships, and unexpected events. The site describes itself as an unofficial fan-made project, not an official or affiliated Project Moon game.

The free simulator uses a seeded rules engine and built-in events. Players can begin with a random resident or customize details such as a name, story language, and seed. Decisions change five fictional attributes and the life that gets saved in the browser archive. A separate paid AI chapter adds generated scenes and cloud saves.

Its clearest distinction is reproducibility: with the same rules version, seed, and choices, the site says a life can be replayed across languages and resident names. The standard mode does not require sign-in or payment. Its optional AI mode is a separate service with separate records and a one-time price.

Key Features

1. Seeded Resident Starts

Start with a randomly prepared resident or customize a name, story language, seed, and rules version. The seed determines the resident's starting background, including family and birthplace. Reusing the same rules version and seed gives players a repeatable starting point; keeping the choices the same reproduces the same life according to the field guide. A seed link shares the beginning, not the saved life record.

Keywords: seeded simulation, replayable life sim, character setup, shareable seed.

Standout: the documented seed-and-choice combination is designed to reproduce a run across supported story languages.

2. Choice-Driven City Simulation

Read life events and choose how the resident responds as education, work, relationships, and career paths unfold. Five status values—health, sanity, resources, connections, and reputation—are shown as fictional indices from 0 to 100. Choices can improve one area while putting another at risk; reaching zero health or sanity ends a life. The displayed resources are fictional and cannot be traded or redeemed as money.

Keywords: urban life simulator, branching events, career paths, five life stats.

Standout: the game makes consequences visible through five tracked attributes while keeping the simulation's resources fictional.

3. Time and Event Controls

The field guide describes four seasons per simulated year, with about one real minute per year at normal speed. Players can pause, slow the simulation, or advance it up to 32×. Keyboard controls include Space to pause, the bracket keys to adjust speed, 1–4 to select an option, and 0 to let an event pass. Major events pause for a decision; minor events can take their final option after a 15-simulated-second timer, which also pauses when the game is paused.

Keywords: browser game, pause control, simulation speed, event timer.

Standout: players can follow a life at a deliberate pace or move through uneventful years faster, while major choices still wait for input.

4. Local Life Archive and Backups

Free lives save in the current browser without an account. The privacy page says the names, seeds, choices, attributes, and life records are stored in browser IndexedDB and are not uploaded. Players can export a backup and import it in another browser to move devices; saves do not automatically sync. An already-loaded game can continue offline, and the guide says a hidden tab pauses the simulation.

Keywords: local browser saves, life archive, backup export, import between browsers.

Standout: the free mode keeps its life records on the player's device and provides an explicit backup path for moving them.

5. Optional AI Chapter

The separate AI chapter is presented as six chapters with recurring characters and consequences that carry forward. It requires an account and a one-time USD $10 pass; the official terms say the pass grants unlimited AI life starts while the service operates, with temporary request-rate and concurrency controls. AI lives use cloud saves and can be downloaded as records. The privacy page says fictional state and recent scenes are sent to DeepSeek, excluding the player's email and resident name. During provider outages, the terms say clearly marked original preset scenes may be used.

Keywords: AI narrative, recurring characters, remembered choices, cloud saves.

Standout: this is an optional cloud-backed story mode layered beside unlimited free local simulation, rather than a requirement for starting a basic life.

How to Use Project Moon Life

1. Open Enter the City, choose a random start or customize a resident, and select a seed, rules version, and story language if desired. The site asks players to confirm they are at least 15.
2. Start a free life. Read each event and choose an available response; use the pause and speed controls to set the pace.
3. Follow the resident's attributes, work, relationships, and events as the years advance. A seed link can be shared when another player should start from the same beginning.
4. Return to the life archive in the same browser, or export a backup before clearing browser data or moving to another device.
5. To use the separate AI chapter, sign in and purchase its one-time pass. Its lives use cloud records rather than the free simulator's local archive.

Use Cases & Who It's For

• Replay and comparison: players can share a seed and compare outcomes while keeping the rules version and choices consistent.
• Short-session storytelling: players who enjoy text events and consequential choices can slow down at major events and speed through other years.
• Career and life-path exploration: fans of life simulators can follow education, work, relationships, and five changing status values over a resident's lifetime.
• Unofficial setting-inspired play: fans of the referenced fiction can explore this site's original writing and art, with the clear understanding that the project is unofficial.
• Persistent AI story play: players who want recurring characters, cloud saves, and AI-generated scenes can evaluate the separate paid chapter.

Pricing & Free Plan

Project Moon Life is freemium. The seeded base simulator is described as free and unlimited, with no account or payment required; the number of records a player can keep is still bounded by local browser storage. The optional AI Chapter Pass costs USD $10 once, with no subscription. The official pricing and terms pages say it allows unlimited AI lives while the service operates. Temporary request-rate and concurrency controls apply. Pricing was checked on 2026-10-16.

Strengths & Limitations

Strengths

• The free core loop does not require sign-in or payment.
• Seeds, rules versions, and choices provide a documented way to replay the same life.
• Local backups make free records portable without cloud syncing.
• The website offers English, Chinese, Japanese, and Korean interfaces and story-language options.

Limitations

• The project is an unofficial fan work and is not affiliated with Project Moon.
• The content is intended for ages 15+ and may include fictional death, illness, crime, and psychological distress; outcomes are not professional advice.
• Free lives remain in one browser unless a player exports and imports a backup. Clearing browser data without a backup can remove them.
• AI play requires an account and payment, uses cloud records, and is subject to temporary rate and concurrency controls. The free simulator and AI archive do not automatically sync or import into each other.
• The supplied /play page is marked noindex, nofollow; the main site and field guide provide more of the publicly readable product details.

Alternatives & When to Choose It

• BitLife is another text-based life simulator built around consequential choices and life paths. Consider it when you want a different text-simulator presentation; choose Project Moon Life when seeded replay and its City setting are central to your interest. BitLife's official site describes the product as a text-based life simulator.
• AI Dungeon is an AI-guided role-play and interactive storytelling tool where players can enter actions or dialogue and have AI continue the adventure. Consider it when free-form prompt-led role-play is the main goal; Project Moon Life's free mode instead documents a seeded, choice-based life simulation. AI Dungeon's getting-started guide explains its turn-based inputs and generated responses.
