In the Era of Gemini 3, How Close Are We to Developing Indie Games as Individuals?

Using Vibe Coding, I built a simulation-style dating and relationship-building interactive map system for the tavern in SillyTavern—and realized: maybe we really can make indie games with AI now!

First, a quick intro to SillyTavern:

SillyTavern is a locally-run AI character chat frontend. You can load character cards, connect to large language models via an API key, and engage in long-term narratives involving RPG, romance, adventure, or nurturing gameplay. It’s more like a programmable text-based game engine.

The plugin I created this time accompanies one of my favorite character cards. The map faithfully recreates, 1:1, the surrounding environment described in the worldbook.

But the real highlight isn’t just its visual appeal—it’s actually playable:

Intelligent Travel System

Click any location to instantly generate a narrative prompt, such as:

invites {{char}} to visit {{location}}

—triggering the AI to auto-generate the next part of the story with one click.

In-Depth Base Exploration

nanobanana drew a detailed vertical layout of the entire base—from the rooftop terrace down to the first-floor lobby—with every floor clickable to enter different rooms.

Highly Customizable

You can swap map backgrounds and drag landmarks to reposition them freely.

Includes three built-in UI themes: Black & Gold, Blue & White, and Pink & White.

Even crazier:

The map was illustrated by nanobanana, while the code was written by Gemini 3 based entirely on my sentence-by-sentence descriptions of the requirements.

When you truly become immersed in a fictional world,

you start wondering:

What if it weren’t just dialogue—but had an actual map?

What if I could click into every floor described in the story?

What if it weren’t just about reading a narrative—but offered more interactive systems to play with?
