Project Mirror Labyrinth Tutorial: Getting Started

Welcome to the ultimate project mirror labyrinth tutorial. This Roblox experience is a tactical, turn-based roguelite deck builder deeply inspired by Slay the Spire, Library of Ruina, and Limbus Company. Set in a mysterious world following the events of Angela's Bad End in Library of Ruina, you do not need prior knowledge of the Project Moon universe to succeed. Your main loop revolves around entering treacherous dungeons, constructing powerful card combinations, and utilizing earned resources to unlock stronger Outfits.

Video Highlights:

  • Fusion Gameplay: Witness the striking blend of Library of Ruina and Limbus Company mechanics.
  • Combat Flow: Observe how attack and defense cards clash in real-time turn-based battles.
  • Lobby Navigation: Locate the key interactive areas including the gacha and dungeon gates.

To begin your journey, you must first launch the game from the Official Roblox Experience Page. Because the game currently lacks controller support, playing with a keyboard and mouse is highly recommended for optimal menu navigation and tactical card selection.

Step-by-Step: How to Run Your First Dungeon

Entering a dungeon and surviving your first few battles can be daunting. Follow this step-by-step pipeline to start your run and build a stable deck.

1

Access the Dungeon Gate

In the main lobby, you can start a run by pressing TAB on your keyboard and clicking Play. Alternatively, walk up to and interact with the physical NO ENTRY gate located in the game world.

2

Draft Your Starting Deck

Upon entering, you will receive a basic set of attack and defense cards. Do not neglect defensive options; blocking incoming damage is crucial for surviving deep runs.

3

Engage in Tactical Combat

Combat is turn-based. Analyze enemy intents displayed above their heads. Play defense cards to mitigate heavy attacks and use your attack cards during openings to whittle down their health.

4

Collect and Spend Fragments

Clear encounters to gather Fragments. Once back in the lobby, spend these Fragments on the Reflection banners to roll for stronger Outfits.

Weekly Maintenance

The developers perform scheduled game maintenance every Tuesday at approximately 2:00 P.M. Server access, dungeon entry, and code redemptions may be temporarily disabled during this window.

Reflections & Outfit Progression Systems

Outfits are the core of your build variety, dictating your stats, passive abilities, and card scaling. You acquire Outfits by drawing them from the Reflection system.

Targeted Reflections

  • Focused Drop Rates
  • Best for target farming
  • Consumes Fragments

Standard Reflections

  • General Outfit Pool
  • Good for beginners
  • Uses standard tickets

Defragment System

  • Unlocks Passive Skills
  • Consumes Condense
  • Enhances overall stats

To help you decide where to invest your hard-earned resources, consult the progression priority index below.

Strategic Advice

Never split your resources evenly across multiple Outfits early on. Choose one high-tier Outfit that fits your playstyle, defragment it to unlock its core passives, and build your entire deck engine around it.
