Roadmap

Where Mimmo Engine is going

What we are building to help you make your visual novel, and in what order.

These are plans, not promises: the order changes with what you tell us and with what really works. The years show the direction, not a release date.

In progress
We are working on it or it starts soon.
Testing
We are checking that we can do it well.
Later
It is in the plan, but not started yet.

Already done

What you can do today

  • Your game in nine languages

    An AI translates knowing who is speaking and the tone of the scene, and you can reread and fix every line.

    Since version 0.46.5, August 2026

  • Automatic playtest

    The program plays your story by itself, walks every possible path and tells you where it breaks.

    Since version 0.46.9, August 2026

  • Mimmo AI on your computer

    A model you download once, that writes and helps with no internet and no cost.

    Available

  • The Mimmo assistant

    It explains how things work, takes you to the right place and suggests additions to your story: you approve them, and undo them in one step.

    Since version 0.47.0, October 2026

2027

From the first click to a finished game

Learning, getting to the end and letting someone play.

  • In progress

    A complete guide to the program

    Every section, block and setting explained in nine languages, with search. The help button in the editor takes you to the right page.

  • In progress

    "How do I…" recipes

    From 40 to 60 practical guides: choices that change the ending, inventory and shop, mini-games, translating, exporting. With screenshots that stay up to date.

  • In progress

    A first game that is easier to finish

    We are looking at where people stop between preview and export, and removing the obstacles one at a time.

  • In progress

    Games ready to share

    A folder with your game and the portable Player: whoever receives it does not have to install anything.

  • In progress

    Games more players can enjoy

    Dyslexia-friendly font, colors for color blindness, menus usable with keyboard and screen reader, larger text.

  • In progress

    A more capable assistant

    More testing with real models and a "continue the scene" command.

  • In progress

    Use Mimmo Engine with your AI tools

    Claude, Cursor and other compatible tools will be able to read your project, check it and playtest the story, without changing anything.

  • Testing

    Your game in the browser

    On a web page, for itch.io and for people playing on a phone. First we check that it holds up.

2028

Bring your stories here, let them play anywhere

Tools for people coming from other programs, and for those who publish.

  • Later

    Bring the story you wrote in Ren'Py

    Dialogue, labels, jumps, menus and images become a Mimmo Engine project.

  • Later

    Publish to itch.io in one click

    From the editor to your account, without going through files.

  • Later

    Go back in the dialogue

    Players can rewind lines, and the speaker portrait stays next to the text.

  • Later

    Your AI tools suggest, you approve

    The additions they suggest (scenes, lines, choices, characters) show up in the assistant: you approve with one click and undo in one step.

  • Later

    A complete technical reference

    File format, script functions, every Extra tool, also downloadable to work offline.

  • Later

    A voice for every line

    One audio file per dialogue, with automatic playback and music that ducks. Later, voices generated on your computer, in the language of the game.

  • Later

    Tools for people who translate by hand

    CSV and XLIFF exchange, fallback fonts for every language, a warning when text overflows the box.

2029

Working as a team, growing the game

For big projects and for people who keep updating them.

  • Later

    Compare and merge two versions

    The writer and the artist work on copies and bring them together without losing anything.

  • Later

    Saved games survive updates

    Add a choice to your game without breaking the games already in progress.

  • Later

    An accessible editor

    Usable with keyboard and screen reader, with a public accessibility statement.

  • Later

    Stats for creators

    How many people finish each path and where they stop, only with the players’ consent.

  • Later

    Blocks of your own

    If you know a bit of code, add a new block to the editor.

Up to you

We are thinking about it

The editor and the Player for these systems too. It depends on how many people ask: every request counts.

Achievements and cloud saves for people who publish their game on Steam.

From the same dialogue, faces of the same character that always look like them. Needs a graphics card.

The AI reads the whole story and flags inconsistencies: who knows what, and since when.

Backgrounds, music and sprites to download from the editor, each with its license clearly shown.

For people coming from text-based interactive fiction.

A place to show games made with Mimmo Engine, and creation jams to make your first one.

If the browser game works and you ask for it, an app to play on a phone.

A kit to teach digital storytelling with Mimmo Engine.
