# About | Big Mech Energy Idle

Big Mech Energy Idle is a darkly comedic idle game about the last loyal AI on Earth, built by **lifeingray**, a solo developer with a fondness for big robots and bigger numbers.

## The design promise

- **Idle first.** The game fights and progresses on its own. Active play optimizes; it never babysits.
- **No dark patterns.** No energy timers, no daily streaks, no fear of missing out. Come back whenever; the mech kept working.
- **Free means free, on the web.** The browser version has no ads, no account and no purchases: nothing to buy, nothing to refund. A future desktop or Steam build is a separate thing and could be priced, but the web game stays free.
- **Numbers you can read.** Every multiplier shows its work. Hover an attack and see the whole formula, [documented in the wiki](/wiki/reading-the-math/).

## How it is built

A deterministic TypeScript core drives the whole simulation; the browser only renders it. The art is procedural PixiJS, drawn from code with no asset files. Big numbers run on break_infinity, saves are versioned and migrate forward forever, and the [save format is documented](/wiki/saving/) so fans can build planners and tools.

## Your data

There is no server. Your save lives in your browser's localStorage and never leaves your machine. Export a save code any time; it is yours.

## Say hello

The community lives in the [Discord](https://discord.com/invite/KFGhGmQWKs): bug reports, build screenshots, balance arguments and the occasional pour celebration. The developer is in there every day.
