longshore

A coast, some fish, and whoever you can hear. Nothing is at stake and nothing decays.

A pixel coast: blue water, a sandy shore, woods behind. Three people along the water. One has a bite, with a red float and ripples. One is cooking at a fire, a ring part way round. One further up the beach is talking.
Hank has a bite. Mira is cooking, the ring part way round. Dave is further up the beach with something to say about it.

What it is

You walk about, you fish, and you talk to whoever else is there.

It runs over LoRa radio on loraline, so the people on the shore with you are the people your antenna can reach. No server, no account, no internet.

Two numbers go up and both are yours alone. How many kinds you have ever caught, which stops moving once you have seen most of them. And your fishing, which goes up with every fish and has no last level: an evening reaches about six, a year about twenty-two.

Neither is ever sent anywhere. If you want to know somebody's you have to ask, and they can lie, and nobody minds. A number on the wire is a leaderboard whether anyone meant one or not.

The opposite of catacomms

catacomms is four minutes, everyone present, every machine agreeing on one room to the byte. That needed turn locking, state hashes and divergence detection, because a disagreement there would matter.

Here nobody is racing anyone and my catch does not change your water. So there is no consensus to reach and no engine to keep in step. You keep your own state, your position rides along on a heartbeat, and a second-old view of where somebody is standing is good enough.

That has a side effect worth having. Somebody at the edge of your range updates slowly and vaguely; somebody standing beside you updates smoothly. How clearly you can see another person depends on how well your radios hear each other.

The coast

A whole coast from above. Small coloured squares mark every place you can fish from, tinted by the water it fishes, and an orange dot marks the fire.
The whole coast, forty by twenty-four. Every marked square is somewhere you can cast from, tinted by what it fishes: open sea, shallows, reeds or a rock ledge. The orange dot is the fire.

Derived from a seed and never transmitted. Everyone who types the same --coast is on the same coastline without a byte crossing the air. Bays, headlands, reed beds, rocks standing out of the water, and the odd island you cannot walk to.

The fish

Forty-two species across four waters. What is biting depends on where you sit, the hour and the month, so a year has a shape and so does an afternoon.

Across a whole coast and a whole year: 40% common, 38% uncommon, 8% scarce, 2% rare, 13% boots and driftwood. A given spot at a given hour is lopsided, which is the reason to get up and walk somewhere else.

A cast is derived from the place, the day, the hour and a salt, so anyone can check that a cast produced what was claimed.

Fishing

Tap the water to fish it and you walk to the nearest place you could cast from, and cast when you arrive. Tap the land to walk. Tap again to strike.

A bite comes in seven to twenty-four seconds, and you have under three seconds to strike. Walking away cancels the cast, and that is the only mistake available to you.

When something takes the float it turns red and throws ripples, and a mark appears over your head so the others can see it. On the strike the name and size float up and fade, and land in your log. Somebody else landing one shows the same way over their head.

What anyone says appears above them as well as in the panel. The page makes its own sounds: a plop on the cast, a knock when something takes it, a lift when you land one. The knock is the one that matters, because you will be looking somewhere else.

The fire

A fire burning on the sand, throwing warm light across the beach. One person stands beside it with a bass on the fire, another warms themselves, and a third is fishing a few paces away with a bite on the line.
Three people at the fire, one of them cooking.

Every coast has one, where the fishing is, and the seed decides where. Nobody places it and nobody is told.

Walk up to it and it is lit. Walk away and it is not. Nobody keeps it going and there is nothing to come back to, so a week away costs you nothing.

Put your last catch on and everyone nearby sees what it is. Cooking gains you nothing and costs you nothing, so it is simply a reason to walk over to where the others are.

Driftwood makes it burn higher for a while, if you feel like putting some on. Driftwood is what you catch when you catch nothing.

What it can't do

A few people, and no strangers

Taking a step sends your position at once, so movement stays smooth however many people are about. What gets slower in a crowd is noticing that somebody has wandered off.

Nobody is going to wander in because they happened to be online. A coast with nobody on it is not peaceful, it is empty.

Fishing, and nothing else

No crafting, no building, no second skill. With four people a second activity splits the group, and being together is the point.

The band is yours to get right

It transmits on licence-free spectrum that differs by country. Read loraline's setup first.

Getting it

longshore is inside the loraline app, in the switcher across the top. One download, one radio, one setup, and the chat on the shore is the same conversation as everywhere else.

You can be standing on the coast a minute after the download finishes. Fishing alone needs nobody to talk to, so it needs no radio.
