Awaken on Hayaku! Island of Darkness without memory, guiding Secsy, the sarcastic cat AI, through puzzles and combat to find your lost brother.
About this game
HAYAKU! is a fast-paced retro-inspired metroidvania set on an island that has been cut off from the outside world.
The game pays homage to classic titles from the 8-bit era.
Explore abandoned laboratories, overgrown cities, crystal mines, military strongholds, ancient forests and the last surviving human settlements. Download map data from forgotten terminals, reconnect transport stations and return to previously inaccessible places as you acquire new movement and combat abilities.
Dash through hazards, cling to walls, bounce from enemies, cross electrical networks and uncover shortcuts, hidden rooms and optional challenges.
Master a dynamic arsenal
Fight with three primary weapons, each built around a completely different playstyle:
Crimson Star: A versatile energy blade for fast, directional combat.
BeastBreaker: A heavy weapon capable of powerful strikes, launched attacks and devastating impact.
TurboDrill: A mechanical chain weapon used to attack, grapple and control space.
Weapons can reach three combat levels, gaining stronger attacks and changing their behavior as they grow. Maintaining that power is part of surviving the island.
A secondary weapon wheel provides even more options. Throw bouncing bombs, rapid daggers and more!. These weapons consume crystals and can interact with your main attacks, enemies and the environment in unexpected ways.
Pilot and customize Power Armor
Board a combat-ready Power Armor with its own movement, health and weapon systems.
Mix cores, arms and legs from four distinct armor families to create your preferred machine. Equip shields, energy cannons, drills, chains, axes and rapid-fire weapons, then combine them with different mobility options such as gliding, hovering, aquatic movement and specialized dashes.
Every combination changes how the armor moves, fights and survives.
Help the island's survivors
The island is still inhabited. Meet travelers, engineers, scavengers, strange machines and communities struggling to endure outside Reikan's control.
Accept favors, follow leads and keep track of your discoveries through the Notes & Favors journal. Optional quests, forgotten recordings, photographs and pieces of Dr. Geno's research reveal stories that the island's rulers would rather keep buried.
Face dangerous enemies and cinematic bosses
Battle malfunctioning defense robots, Reikan soldiers and mutated creatures known as Tenebris.
Each region introduces its own enemies, environmental hazards and traversal challenges. Large-scale boss encounters combine demanding combat with elaborate pixel-art animation, dramatic camera work and powerful visual effects.
Uncover the truth behind Hayaki
Hayaki awakens inside the Forgotten Lab with no memory of who he is or how he got there. His only companion is Secsy, a sarcastic security AI contained inside a cat-shaped robotic mask.
A fragmented memory gives him a name: Yusuke, a soldier Hayaki believes to be his missing brother.
Their search leads across an island ruled by Reikan, an organization that promises protection while controlling its people, resources and history. As Hayaki learns more about the Tenebris and his own impossible abilities, the difference between monster, human and machine begins to disappear.
How deeply you confront the island's past will shape its future.

The Hayaku devblog is live!
Some news: Hayaku! has a devblog now. For real this time. We've been saying "next month we start the blog" for approximately three years, and the month finally arrived.The first post tells the story of the biggest thing that happened to Hayaku since it exists: we rebuilt the whole game. Hayaku started as the personal Construct 3 project of our artist Ezequiel, made alone in his free time, and it grew until it had a whole island, a mecha with interchangeable parts, and an engine that couldn't hold it anymore. By the end of 2025 the situation was untenable and we took the decision every developer fears in public and dreams about in secret: porting everything to Unity. That was nine months and 1,700 commits ago. At least thirty of those commits are called "fix". One is called "fix fix". We don't talk about that one.The hard part was not the code, it was the feel: making the new version move exactly like the game people played at events, which took rebuilding the movement system more times than I want to admit in a public post. But the game is back on its feet, it feels better than those demos, and it came back with new things: a fast travel network, new weapons including a drill that grapples to ceilings and lets you swing like an idiot, meaner enemies, and display filters that make the whole game look like a CRT or a Game Boy, because there is no producer here to stop us.Wanna hear the whole story?
