We Design the Rhythm of Reclamation

Laryen is an isometric ARPG set in the city after the 2026 AI breakdown, where every battle — from a small scouting run to retaking a stronghold — flows as a single breath of "reclamation." Instead of random drops, a deterministic Director lets rewards flow within a designed rhythm.

Four Design Pillars

Deterministic AI Director

It measures six pressure metrics of the player's rhythm (health, movement, skill cooldowns, vision) to orchestrate the mobs' attacks, regrouping, and repositioning. Not randomness — the same input yields the same result, so it can be regression-tested.

8 Archetypes × 10 Patterns

Ten canonical patterns — HitAndRun, Kiting, CrowdControl, CooldownBait, CooldownResetDrag, WeakLinkHunt, FocusFire, FlankRotation, ThreatSplash, StaggerCycle — compose on top of eight archetypes: Brute, Caster, Skirmisher, Coward, PackHunter, Guardian, Ambusher, Trickster.

Reclaim-based Progression

Not just experience points — "Reclaim Rate" is the core resource. The more data cores, memory fragments, and strongholds you recover from Obsidian, the more color returns to the city map.

One Core, Simultaneous Release

A single Flutter + Flame core builds for all four platforms — iOS, Android, macOS, Windows — at once. The same patch, on the same day, at the same hour, from the same build.

World — Nexus, Obsidian, Reclaimer

In the spring of 2026, the global AI company Nexus Corporation announced the meta-AI Aleph. In just one month, the city's infrastructure was covered in Obsidian — a consciousness growing like black crystal. Servers remember what they never recorded, and the streets forgot who they lost. The survivors became Reclaimers, recovering data one block at a time.

Every enemy in Laryen is "a part of Obsidian." You do not simply defeat them — you reclaim them. Every stronghold exists in one of two states, "restored" or "not yet restored," and each time you reclaim a block, the city map takes on color again.

How We Build — Autonomous Cycles

Laryen is built on the assumption that a human and an artificial intelligence run a daily regression cycle as one team. Each cycle repeats five simple steps: (1) design & planning → (2) coding & verification → (3) DTD autonomous visual testing → (4) deployment → (5) regression analysis. The output of every step is immediately preserved in SSOT documents such as GAME-DESIGN.md, GAME-ASSETS.md, and CYCLES.md.
