Whale Island
Where it starts. Fish, sell your catch, earn your first Jenny, find the captain and win your ticket to the exam.
Pass the Hunter Exam, climb a 200-floor fighting tower, awaken your aura and find your place in a city run by the mafia. An action-RPG about the discipline of Nen, built by an independent studio.
Each region is its own chapter. Players arrive by boat or train, take on the local quests and move on when they are ready.
Where it starts. Fish, sell your catch, earn your first Jenny, find the captain and win your ticket to the exam.
A shared server-wide event every two days: a 12-minute endurance run, a tower duel against the assassin Johness, then pools and a losers' bracket for the licence.
A ranked 1v1 arena. Win to climb ten floors, lose to drop. Matches run five minutes on a giant screen, with a lobby where anyone can spectate.
The hub. Seven districts, an elevated train, mafia families, bounty boards and the hideout of a dangerous troupe of thieves.
Fights are fast and readable. Every heavy attack is telegraphed, every stun has a window, and a perfect parry turns the fight around.
A master places a leaf on a glass of water. What happens when you focus your aura reveals your affinity, saved separately on each character slot.
After the awakening, each technique has its own training quest: Ten, Zetsu and Ren at the tower, then Gyo, In, En, Shu, Ko, Ken and Ryu in Yorknew.
A timed world event. The auction house opens for one hour and sells exclusive items that cannot be found anywhere else, at prices only the richest players can reach.
Found your own organization in Yorknew, invite members and carry its name above your head, or hide it in the settings.
Two rods, rare catches worth more, a breath gauge under water and fish that actually swim like fish.
Secrets of Nen is designed, modelled and play-tested by one developer. The code is written and tested by AI agents built on Anthropic's Claude, working directly inside Roblox Studio and checked at every step.
Turns each request from the creator into short tasks with measurable goals, and keeps the live dashboard up to date.
Several agents work in parallel, one area each, inside Roblox Studio. Every change is backed up first.
A separate agent plays the game and measures damage, distances, timings, saves and multiplayer before anything is accepted.
Checks the whole pipeline every ten minutes, restarts stalled work and keeps it running through the night.
