About This Game

You don't catch Echoes. They choose to join you.

In a city of the future, two apprentices watch over the Clock that governs the passage of time. Pull the lever even a little too soon, and time will be shattered, and you’ll find yourself deep in the past.

You wake up in a Stone Age camp, with no memory of how you got there. The Elder entrusts you with your first Echo, a small creature that only lives in this age. And there's Saël, another traveller dropped out of time like you, who is already itching to challenge you. All that's left is to mend what was broken, era by era, and find your way back to the future.

• Explore open worlds: living villages and towns, caves and their guardians, lakes, deserts and mountains — and everywhere, wild Echoes roaming the land or tracing their path across the sky.

• Fight turn-based battles alongside your team. Eleven types of Echoes — from Fire and Ice to Storm, Shadow or the very rare Chrono — each with its own strengths, weaknesses, and its own way of turning a fight around.

• Earn their trust: after a victory, a wild Echo may decide to follow you. Those who don't find a place on your team will wait patiently in the Echo Stone.

• Grow together: level up, learn new moves, and watch them evolve. Sometimes nature even offers a rare, shimmering form — keep your eyes open.

• Ride them: once an era's story is over, its Echoes carry you, and transports of the age link its towns.

• Push the doors open: huts, temples, villas, baths… every place has its people, and every person their secrets.

Your team, levels and bag follow you from one age to the next — and you can return to the eras you've visited whenever you like. But between us, the journey never quite goes as planned…

Early Access (2027) already includes at least four eras, each with its own story, map, music and 37 Echoes: the Stone Age, Ancient Greece, the age of dinosaurs, Gallo-Roman Gaul… and the ones that will have joined them by then. Dozens more will follow through updates, all the way back to the future.

The demo contains the whole first chapter, the Stone Age. Playable in English and French, with keyboard or gamepad. See you there.

AI Generated Content Disclosure

The developers describe how their game uses AI Generated Content like this:

Each creature (Echo) is inspired by real animals, objects and myths of its era, following real evolution: the Greek lion is a descendant of the prehistoric sabre-tooth, the Gaulish bull of the aurochs. Some creature and character sprites and animations started from AI pixel-art generators (PixelLab, SpriteCook). Others were drawn procedurally with code or adapted from CC0 resources. All were hand-edited and refined by the developer.

Buildings and environments are based on real-world historical architecture and on permissively licensed open-source assets (CC0, CC-BY and other non-copyleft licenses), adapted, recreated and hand-edited into pixel art. No AI tools were used to generate the architectural artwork.

The soundtrack is built upon open-source and Creative Commons compositions sourced from OpenGameArt, transformed, given new timbres and procedurally processed with custom Python scripts and algorithmic audio tools to fit each historical era.
The storyline, dialogues, creature descriptions and English translation were drafted with the assistance of AI writing tools, then directed, manually reviewed and rewritten by the developer.
No AI content is generated while the game runs.

Name of AI model included with the game: PixelLab and SpriteCook (pixel-art sprites and animations); Claude by Anthropic (writing assistance and English translation)
