What Is Project Mirror Labyrinth?
Project Mirror Labyrinth — running on place ID 116276659864007 — is a roguelite deck-builder that wears its Project Moon inspirations proudly, drawing on Library of Ruina, Limbus Company, and Slay the Spire. You play a special kind of card game: each run, you enter a procedurally generated mirror labyrinth, fight turn-based battles, and build a deck of cards that grows more powerful as you go. Between the strategy, the puzzles, and the post-Ruina mystery, it is one of the more thoughtful games on Roblox.
Made by the Project Mirror Labyrinth group and created in November 2025, it has already passed 8.8 million visits and holds a remarkable 97% rating — one of the highest of any recent Roblox release. It is still in alpha, so content and balance are actively evolving, but the core deck-building loop is already sharp and rewarding. You do not need to know the Project Moon games to enjoy it; the systems teach themselves as you play.
How the Game Works
The loop is a classic roguelite. You start a run, enter the labyrinth, and progress through procedurally generated stages, choosing your path as you go. Each encounter is a turn-based card battle where you play cards from your deck to attack, defend, and use effects. Winning lets you draft new cards and upgrades, so your deck gets stronger and more specialized deeper into the run.
When you fall, the run ends — but you carry meta-progress forward, spending currency to unlock cards and outfits that make future runs stronger. That tension between a single risky run and long-term growth is the heart of the genre, and Project Mirror Labyrinth executes it with real strategic depth and a striking mirror-and-reflection theme.
Deck-Building Strategy
Winning is about your deck, not luck. A few principles carry every run:
- Stay focused. A tight deck built around one or two synergies beats a bloated pile of "good" cards. Skip cards that dilute your plan.
- Thin your deck. Removing weak starter cards makes you draw your power cards more consistently.
- Match cards to the fight. Adjust which cards you draft based on the enemies and bosses ahead.
- Value defense. Surviving to the late run matters more than raw damage — blocks and heals keep your snowball rolling.
- Plan your path. Choose labyrinth routes that fit your build and resources, not just the shortest one.

Fragments & Currency
Fragments are the main currency. You spend them on Reflections and to draw new outfits and cards without paying real money — the core way you expand and improve your collection between runs. The game also uses Condense and rarer rewards like Seed of Light (granted by the Welcome code). Because Fragments gate so much of your progression, banking them early is a big deal, and that is exactly what codes are for.
Project Mirror Labyrinth Codes

Fragments are the main currency. You spend them on Reflections and to draw new outfits and cards without paying real money, which is how you expand and improve your deck between runs.

No. It is a skill-and-strategy roguelite where deck-building and smart play decide runs, not spending.
