How It Works

Memory Palace meets Pirate Adventure

Dead Reckoning uses the Method of Loci — an ancient memory technique where knowledge is stored in vivid spatial locations — and turns it into a pirate game. You don't read definitions. You stage knowledge into the world.

The Big Twist

Captain Nemo and Bit staging AI concepts into island landmarks

You don't collect knowledge. You stage it.

Spatial association, not flashcards

Every AI concept is mapped to a vivid, memorable physical object in the game world. When you place a concept, you're creating a spatial memory — exactly how the Method of Loci has worked for thousands of years.

  • Training Data → fish crates on the dock
  • Model → captain's navigational chart table
  • Inference → a loaded cannon, ready to fire
  • Overfitting → a treasure chest covered in barnacles
  • Feedback Loop → a tidewheel that cycles endlessly
🧠

Method of Loci

Used by memory champions for millennia. You walk through a familiar place and "deposit" memories at specific locations. Later, you mentally walk the same path to retrieve them.

In this game, the pirate islands ARE your memory palace.

The Core Gameplay Loop

Captain Nemo and Bit moving through the core gameplay loop

Every island follows the same satisfying 5-phase rhythm

Phase 1 · 5–10 seconds

⛵ Arrival

Your ship auto-docks at a new island. The island name appears carved into a signpost — no UI overlay, pure environmental storytelling. The camera frames the island in portrait view, building anticipation.

Phase 2 · 60–120 seconds

📍 Exploration & Encoding

Walk between 3 landmarks. Each reveals one concept card. Place the concept into its landmark — "Training Data" drops into the fish crates, "Model" unfolds on the chart table. This is a safe sandbox — no threats during encoding. Take your time and build strong spatial associations.

Phase 3 · 5–10 seconds

⚡ Encounter Trigger

The sky darkens. The sea churns. Fog rolls in, lightning cracks, or a red sail appears on the horizon. The environment transforms to signal danger — and the recall phase begins.

Phase 4 · 30–90 seconds

🎯 Recall Sequence

Icon-based spatial riddles test your memory. "What feeds the learning?" shows a fish icon and an empty crate — you must tap the Dock Crates landmark. Difficulty climbs within the encounter. Novice assists activate after failures; expert paths reward perfection.

Phase 5 · 10–20 seconds

🏆 Resolution & Reward

Threat defeated! Earn a Chart Fragment, ship upgrade, or rare relic. Watch the sea chart fill in. See a preview of the next island as a silhouette on the horizon. The cycle begins again.

Combat System

Captain Nemo and Bit facing island enemies in combat

Pokémon-style turn-based battles against island creatures

Charge-meter combat

While exploring islands, you'll encounter enemies — crabs, jellyfish, burrowers, and more. Touching an enemy triggers a turn-based combat overlay inspired by classic Pokémon battles. You have two options each turn:

  • ATTACK — instant strike dealing ~34% of enemy HP
  • CHARGE — hold the button to fill a power meter, then release for up to 2× damage. Time it right for maximum impact.

After your turn, the enemy retaliates. Three well-placed attacks defeat most enemies. On victory, your HP refills and you earn +100 bonus points plus a Skill Point.

⚔️

Risk vs Reward

Quick attacks are safe but slow. Charged attacks are devastating but leave you vulnerable if you mistime. The charge meter fills over 1.2 seconds — overshoot and you waste a turn.

Master the charge timing for one-shot kills with the right skill upgrades.

Skill Tree

Earn Skill Points through combat and learning — invest them to power up

⚔️

Sharp Cutlass

+20% attack damage per level. 3 levels available. The foundation of the Offence branch — makes every strike hit harder.

Offence · Cost: 1 SP
⛨

Iron Hull

-20% damage taken per level. 3 levels available. The foundation of the Defence branch — each enemy hit stings less.

Defence · Cost: 1 SP
⚡

Swift Charge

+20% charge speed per level. Fills the power meter faster, letting you execute devastating charged attacks more quickly.

Offence · Cost: 2 SP
❤️

Sea Legs

+10% max HP per level. More staying power in extended fights. Stack with Iron Hull for near-invulnerability.

Defence · Cost: 1 SP
🌩️

Thunder Strike

+0.5 maximum charge multiplier per level. At max level, a fully charged attack deals 3× base damage — enough to one-shot most enemies.

Offence · Cost: 2 SP
💰

Plunder

+50 victory points per level. Turn every combat victory into a score multiplier. Chase the leaderboard with maxed Plunder.

Offence · Cost: 2 SP

Earning Skill Points

Skill Points are earned through two activities:

  • +1 SP for defeating an enemy in combat
  • +1 SP for placing a concept at its landmark

This means exploration and learning are just as rewarding as fighting. A player who carefully places all concepts earns as many upgrade points as one who battles every enemy. 21 total SP are needed to max every skill.

🌲

Two Branches

Offence: Sharp Cutlass → Swift Charge → Thunder Strike, with a Plunder side-branch.

Defence: Iron Hull → Sea Legs.

Prerequisites gate deeper skills. You must invest in basics before unlocking the powerful tier-2 and tier-3 abilities.

Island Enemies

Captain Nemo and Bit scouting island enemy types

Creatures escalate in complexity as you progress through the archipelago

Enemy First Appears Behaviour Elite Variant
🦀 Crab Island 2 Patrols between landmarks — the introductory enemy 🔥 Fire Crab (faster, tougher)
🪼 Jellyfish Island 3 Drifts vertically — adds a second patrol axis 👻 Shadow Jelly (harder to spot)
🐛 Burrower Island 4 Hides underground, emerges near the player — surprise attacks 🐍 Sand Wyrm (faster, wider range)
🦔 Urchin Elite only Stationary area denial near landmarks — blocks access —
🦈 Phantom Ray Elite only Long diagonal patrol covering large areas — fast and dangerous —
🛡️

Performance Scaling

Enemy spawns adapt to your skill. D-grade players face fewer enemies (novice assist). S/A-grade players face elite variants plus extra spawns like Urchins and Phantom Rays.

💨

Shield Powerup

Found scattered across islands, the shield powerup absorbs one enemy hit — letting you pass through without triggering combat. Strategic players use shields to skip tough encounters.

Fair Failure

Fail fast, retry faster — always under 5 seconds back to action

⏱️

5-Second Retry

Every fail state in the game gets you back to the action in under 5 seconds. No long game-over screens. No reload. Quick animation, immediate retry.

🦜

Novice Assists

After 2 failures on the same prompt, your parrot Bit flies toward the correct landmark. Fog slows down. Lightning holds its flash longer. The game helps without telling you the answer.

⭐

Expert Mastery

Get everything right on the first try? Unlock hidden chambers, rare relics, bonus score multipliers, and ultimately the secret Hidden Reef island.

Ship Upgrades

Your ship the Loci evolves as you progress — rewards make recall more forgiving, not more powerful

Island Upgrade Effect Rarity
Island 1 — Tutorial island, no upgrade —
Island 2 Reinforced Mast 1.2× sailing speed, Bit flies faster during assists ● Common
Island 3 Enchanted Cannon +1 error tolerance in pirate battles ● Uncommon
Island 4 Ironclad Hull +1 storm hit resistance ● Rare
Island 5 Golden Compass +2s recall window on all encounters ● Epic
All Expert Bonuses Ghostlight Lantern Reveals the Hidden Reef secret island ● Legendary

Concept ↔ Metaphor Examples

Captain Nemo and Bit connecting AI concepts to world metaphors

Every concept has a vivid physical metaphor — not a definition, but a memorable object

AI Concept Metaphor Object Landmark Why It Works
Training Data 🐟 Fish crates full of sample catches Dock Crates Data is the raw material — just like fish in crates
Model 🗺️ Captain's navigational chart Chart Table A model maps patterns — just like a chart maps the sea
Inference 💥 Loaded cannon ready to fire Cannon Inference fires a conclusion — aim and shoot
Bias 🧭 Crooked compass Compass Pedestal Always points slightly wrong — systematically off
Overfitting 🪸 Barnacle-encrusted chest Barnacle Chest So over-decorated it won't open — too specific, too rigid
Neural Network 🕸️ Signal ropes connecting mast lights Rigging Web Nodes (lanterns) connected by ropes, each lighting on signal
Gradient Descent ⚓ Anchor lowering step-by-step Anchor Winch Finding the lowest point — one deliberate step at a time

Play on phone or PC — every interaction works on both touch and keyboard/mouse

📱

Touch / Mobile

Portrait-first design. Primary actions in the lower ⅓ of the screen (thumb reach zone). Hazards in the upper ⅓. Tap to select, drag to place, swipe to navigate.

🖥️

Mouse & Keyboard

Click to select and place. Arrow keys or WASD to navigate. Keyboard shortcuts for quick recall. ±20% time parity with touch — neither input feels disadvantaged.

DLC Gameplay Modes
