Project Mirror Labyrinth is a roguelite deck-builder on Roblox heavily inspired by Slay the Spire, Library of Ruina, and Limbus Company, set shortly after Angela’s Bad End in the Project Moon universe. The Upper Library update pushed the game past 5.5 million visits and 23 thousand favorites, with maintenance every Tuesday around 2 PM keeping the meta moving.
You start a run by pressing TAB and Play (or interacting with the No Entry gate), then push through procedurally generated dungeon floors stitching together cards, reflections, and Mirror upgrades into a deck that has to survive the boss. Combat is turn-based and Project Moon flavored: speed dice, page archetypes, and Reflection currency that you spend on permanent upgrades between runs.
This guide walks first-run pathing, the early Reflection priority list, and how to read enemy intents so the deck builds you commit to scale into the late floors. Note that the game has no controller support, so play it on PC or mobile touch.

How to Play Project Mirror Labyrinth
- Create your character and select a starting class or ability set from the menu.
- Follow the opening quest chain to unlock your first combat abilities and the skill tree.
- Farm low-level enemy zones to build EXP and starting currency.
- Invest currency into the skill upgrades that fit your chosen playstyle.
- Push into higher-level zones as your stats and gear meet each area’s recommended threshold.
Project Mirror Labyrinth Gameplay and Strategy
Character builds in Project Mirror Labyrinth open up once you have enough skill points to put into one direction. The early game feels similar for all playstyles because skill variety is locked behind EXP milestones. Pick your build direction before you hit those milestones so you know where to send your points.
Enemy density and EXP rate make some zones much better for farming than others. The best farming spots are usually just below your current level, where kill speed is fast and drops are still worth having. Pushing into areas where enemies take forever to kill often means worse results per hour.
Boss farming gives the best EXP and item drops in Project Mirror Labyrinth but needs a character strong enough to survive. Building for boss fights, either through faster damage or defensive stats, makes late-game grinding more consistent and lets you hit the best loot spots without dying all the time.
Tips for New Project Mirror Labyrinth Players
- Do not spread skill points across every ability early. Specializing in two or three abilities that work together produces better results than spreading thin.
- Farm enemies two levels below your cap for the best kill speed to EXP ratio. Struggling on high-level enemies often feels slow despite better rewards.
- Complete side quests alongside the main chain. They give EXP and currency that compound into faster progression without extra grind.
- Save rare currency for skill upgrades with passive effects. Passive bonuses work without input and stack quietly over long sessions.
- Join a party for boss encounters once you are ready. Boss loot split across a group still outpaces solo zone farming in most RPG formats.
