What Is This Game?

Not a quiz with a pirate theme. A pirate game with memory as its core mechanic.

🏴‍☠️

Pirate Fantasy

You are Captain Mnemona "Nemo" Vex, a pirate-cartographer sailing a shattered archipelago called the Memory Sea. Chart forbidden knowledge and prove that structured memory beats brute force.

🧠

Method of Loci

The ancient memory palace technique — made real. Each island is a locus. Each landmark stores an AI concept. Place knowledge spatially, then recall it when danger strikes.

🤖

Real AI Concepts

Learn Training Data, Neural Networks, Gradient Descent, and 12 more foundational AI/ML concepts — not through text, but through vivid spatial metaphors you'll actually remember.

⚔️

Action, Not Trivia

Recall is your weapon. Fire cannons by remembering where you stored "Inference." Push back fog by recalling concept-landmark pairs. Fight the Kraken with everything you've learned.

🎮

8-bit Aesthetic

Clean pixel art, bold colors, punchy animations. Portrait-first mobile design with full PC keyboard/mouse parity. Plays great on any device.

⚔️

Turn-Based Combat

Encounter crabs, jellyfish, and burrowers while exploring. Fight in Pokémon-style charge-meter battles. Earn Skill Points to unlock a 6-skill upgrade tree with Offence and Defence branches.

🏆

Progression

Earn chart fragments, ship upgrades, and the legendary Golden Chart. Unlock secret islands. Compete on the leaderboard. Earn the title of Dead Reckoner.

The Core Loop

Every island follows the same satisfying rhythm

Core gameplay loop from arrival and exploration to danger and recall

1. Sail & Explore

Arrive at a new island. Discover 3 vivid landmarks — a dock with fish crates, a chart table, a loaded cannon. Each one holds a concept waiting to be placed.

📍

2. Encode

Place each AI concept in its landmark using spatial association. Training Data goes in the fish crates. The Model goes on the chart table. No text — pure spatial memory.

3. Danger Strikes

A cursed fog rolls in. A storm erupts. A rival pirate attacks. The environment shifts — and you must recall what you just learned to survive.

🎯

4. Recall & Resolve

Answer icon-based spatial riddles under pressure. Fire cannons, push back fog, unlock ruins. Correct recall = victory. The chart grows. The next island awaits.

Face These Threats

Five encounter types, each testing memory in a different way

🌫️

Cursed Fog

A supernatural fog that erases knowledge. Push it back with correct concept-landmark recalls before it consumes the island.

Island 1
⛈️

Storm

Lightning flashes illuminate landmarks for a split second. Identify the correct concept before the thunder rolls in.

Island 2
💥

Rival Pirate

Captain Null pulls alongside for a cannon duel. Each correct recall fires a cannonball. Each failure takes a hit.

Island 3
🏛️

Ruins

Ancient chambers with locked doors. Place concepts in the correct sequence — the first multi-step recall challenge.

Island 4
🦑

The Kraken

The legendary giant squid wraps your ship. Each tentacle is a concept from a previous island. The ultimate cumulative test.
