Your gym grows.So do your problems.

You buy a damp cellar and try to turn it into a real gym. The machines break down, the members hog them, the influencers film everything. Good luck.

The Voice · Speaker 1New sign-up: Linh. Welcome. See you in three weeks. Or not. A new employee has joined the team. Please don't tell them the truth just yet.
Coming soon to SteamSteam page planned for November 2026.
01 / The game

The game

Isometric view, toy-like look, chibi characters. Every chapter is a new gym with its own headaches.

01

Proper management

Machines wear out and die, electricity isn't cheap, staff want their pay and members expect something for their money. Drop below -$1,000 and you're bankrupt. If you'd rather take it easy, there's a sandbox mode.

02

Annoying members

Broccoli heads park themselves on a machine for up to an hour to answer one text. The Old Iron Guy has been judging everyone since 1989. You get to send in the coach.

03

A reputation

Three meters follow you from chapter to chapter: Hype, Credibility, Atmosphere. Reshare a shady influencer and your hype shoots up, but your credibility remembers.

04

The Voice

A narrator on the gym's PA. She comments on everything, especially the things you hoped she'd miss.

02 / Try it

Pumpfeed

Your gym's social network, on the manager's phone: fake followers, dodgy influencers and a reply to write. Try it.

THE GYM FEED

@FitGourou_12k tagged you. 12,000 followers, 9,000 of them dodgy. He wants to film in your gym.

The meter values come straight from the game. The tag is made up for this demo.

03 / The people

The people of the gym

Staff doing their best, and members who aren't all here for the workout.

Staff

The Coach

Sent in when a broccoli head hogs a machine. It works about 7 times out of 10.

Member

The EgoLifter

Films himself before, during and after every set. The sets are secondary.

Staff

The Technician

Fixes the machines before the one-star reviews start rolling in.

Staff

The Other Technician

She's seen worse than your cellar. And she'll tell you.

Staff

The Cleaner

The shine is his doing. The stickiness is yours.

Visitor

The Inspector

A clipboard, a stern look. Making friends isn't part of the job.

Staff

The Front Desk

Without her the gym doesn't open. It's in the rules.

Member

The Regular

She actually comes to work out. She's in a very small minority.

04 / The machines

The machines

Ten machines for chapter 2, built in Blender, each in three states: Classic, Modern, Rusty. Here are five.

05 / The gyms

Chapters

Two gyms to start, each with its own look and its own problem.

The Cellar: a member in the squat rack, the placement zone in cyan.
Playable

Chapter 1 · The Cellar

Brick, green tile, pipes and a bit of neon. The machines are second-hand, the coach is exhausted, the reviews and the bills keep coming. Your job: turn it into a real gym.

Concept art of the Fitness 2000 gym: Memphis carpet, mirrors, machines and neon sign.

In development

Chapter 2 · Fitness 2000

A 90s neighbourhood gym, bought along with its 120 regulars. Hype brings in new people, and the newcomers annoy the ones who were there first. You get ten new machines, house rules and Pumpfeed, which will make you regret some of your replies.

06 / What's next

Roadmap

These dates are targets. If we have to slip to ship a better game, we'll say so here.

  1. November 2026

    Steam page opens

    Add the game to your wishlist. It helps us more than anything else.

  2. Early 2027

    Free demo

    Try the Cellar before you buy.

  3. Spring 2027

    Early Access

    Chapters 1 and 2, sandbox mode, in French and English. Tell us what drives you up the wall, it'll steer what we do next.

  4. After that

    New chapters

    More gyms and more headaches, announced in the devlog before they ship.

How it's made

We've been at this for months: the chapter 2 map, its ten machines and their animations in Blender, then the assembly in Unity. There's generative AI in the starting concepts, the posters, the characters, the narrator's voice and the music. The jokes are about behaviours. No real names, no real brands.
