About:
A seafaring risk-and-trade game in the spirit of the 1980s/90s market-running classics, reframed around legal scarce goods and made in-house for Leetdom. You run a small courier boat with a loan to clear and a fixed handful of days to turn it into a fortune. There are no image or audio files in it at all: every island, good icon, wave and sound is drawn or synthesised in code.
Five islands each produce some goods cheap and want others dear, so there is always a buy-here, sell-there run to find: Sea Salt and Lamp Oil pour out of Saltmarsh Flats, Spice Tea and Indigo Dye out of Greenreach, River Pearl out of Coral Shoals, Bolt Silk out of Loomhaven, and Harrow Quay is home, the only port with a guild lender and a chandler to enlarge your hold. Prices swing every day on their own — the market never reacts to your trades — so the structural edge between islands is thin enough that daily noise can erase it, which is what makes every crossing a gamble worth reading up on first. Cheap bulk goods eat hold space; dear goods eat your cash; the squeeze between the two is the whole game.
Setting sail spends a day and moves the market. Storms can cost you an extra day and spoil part of your largest cargo; customs cutters levy a duty when you make port. Harbour talk is tomorrow's forecast — a spike here, a glut there, a storm warning, an inspection — reliable but never complete, so you trade on partial information. Your loan compounds every day at sea whether you are earning or not, and at the final day the boat is settled: debt is cleared against your cash and cargo, and your net worth sets your rank from deckhand to tide-lord. Pick a Short Run, a Trade Season or a Long Haul, and every voyage has a deal number you can replay or hand to a friend to sail the exact same weather and markets.

Lemon StallRun a tiny street-corner drinks stall for a fourteen-day summer fair. Read the forecast, buy lemons, sugar, ice and cups, mix a recipe, set a price, then watch the street decide, and learn from a hindsight chart of what every price would have earned.
Spore QuarantineA spore bloom is spreading across the isles and the Council is watching. Survey the ones you can't read, fund labs toward a cure, route supplies, and seal the worst lanes — all while the wind carries the bloom downwind and public trust runs out faster than funds.
Word BugsTrace a path across touching letters to spell words and strike the ink pests crawling over a living page. Every pest shows its hit and the beats until it strikes, so you choose what to spell and who to aim at. Five chapters, longer words hit harder, and a five-letter word leaves a charged tile behind.
