A co-op arcade game from Melachim Imoveis Ltda

Stormlings: Rios Voadores The Flying Rivers — co-op arcade platformer

Trap the storm. Ride the current. Break the chain.

Seal unruly storms into pressure cells, link them, and bring the whole room down in one readable chain. Single screen, built for co-op.

Windows · Free demo coming soon · Premium game planned, no ads

The Pressure Lattice

One move. Three decisions.

Every stormling you seal becomes a pressure cell. What you do with it is the game.

Cells that wait too long rupture and the stormling returns angry, so choose.

Every state reads by shape, rhythm and glyph, not by colour alone.

Four Keepers. Same moves, different style.

Masked couriers of a sky-foundry maintenance chain. Pick two to play together.

Kite — The opener. Seals first and makes footholds for everyone. Reads the current before it shows. Rushes in, laughs when it goes wrong.

In the demo
Mica — The linker. Places cells so they join into big chains. Hears when two cells are about to link. Methodical, ironic, panics quietly.

In the demo
Vane — The anchor. Holds the door, rescues partners, keeps a zone. Calm and protective; takes every joke literally.

Full game
Lull — The acrobat. Small, jumps high, bounces exactly. Talks to the creatures. Afraid of thunder, goes anyway.

Full game

Tap a Keeper to hear what they say. Roles are style and story: every Keeper has the same verbs. Kite and Mica are planned for the demo.

Follow the water across Brazil.

Episode 1 is inspired by Brazil's skies and landscapes: sea mist, flying rivers, storms. The foundries are ours; the weather is real.

Atlantic coast

Sea mist, copper cranes, a quiet dock at dawn. Where you learn the trade.

Illustration: a glass walkway in the rainforest canopy with golden light and rivers of vapour

First glimpse in the demo

The canopy

Light through glass and leaves, rivers of vapour overhead. The lattice becomes spectacular.

The dry heart, by night

Wide skies, dry grass, distant lightning. The pressure builds.

Trancachuva

A storm front knotted into an old foundry vault. The rain cannot pass. Someone has to untie it.

Places are imagined and generic.

Two Keepers. One chamber. One perfect chain.

Choose any two of the four Keepers.
