The
game

A classic text RPG, powered by AI.

Dungeon Text is a browser-based RPG that combines classic text-driven adventures with AI-powered storytelling and retro-inspired pixel art. An AI Game Master narrates the story, reacts to the player’s choices and keeps track of attributes, inventory and progress.

Created for a Bubble development challenge hosted on Contra, it won the Best Design Award. I was the only UX/UI designer on the project.

02 / Challenge & process

One week,
three days of design

From an AI prototype to a complete game experience, fast.

The challenge lasted one week. AI helped mostly at the start: a first prototype built with Bubble’s AI. From there, the iteration moved to Figma, where the entire visual identity and user experience were designed in three days.

All the illustrations were drawn by hand in pixel art, with no AI image generation.

01AI prototype

A first version built with Bubble’s AI to test the concept and the main flow.

02Game rules

World lore, ten character classes, six attributes and the Game Master’s instructions.

03Figma iteration

Flows, screens and a compact design system, refined from the prototype.

04Pixel art

Hand-made illustrations for campaigns, characters, the Game Master and items.

Rules for
the Game Master

Designing the rules the AI plays by.

The experience also depends on what the AI is told. The Game Master follows a set of instructions: a dark fantasy world lore, the character classes, the campaign, and strict rules to respect saved story events, inventory and attributes, always ending each turn with three possible actions.

Decisive actions are settled by a dispute: a roll from 0 to 20 against the character’s attribute. The lower the roll, the better the outcome; the higher above the attribute, the harsher the consequence.

From character
to story

From character creation to interactive storytelling.

The experience guides players through campaign selection, character creation, attribute distribution and a personal backstory before the adventure begins. During gameplay, a structured interface brings AI storytelling, player choices, character information and inventory together. The goal was to make a traditional text RPG feel accessible, engaging and visually immersive.

01Choose a campaign

Campaign cards with art, lore and popularity, so players can start before even logging in.

02Choose a character

A carousel of pixel art portraits, introduced by the Game Master.

03Distribute points

Spread the initial points across the six attributes, with the character’s history in view.

04Personal backstory

Players add their own detail to the character’s story before the campaign starts.

05Role play

Story, choices, character sheet, life, inventory and the dispute roll in one screen.

06Save progress

Before leaving, the Game Master invites players to log in so their adventure is saved.

05 / Visual identity & design system

Classic RPG,
reimagined

Classic RPG aesthetics, reimagined for the web.

Dungeon Text draws on early computer RPGs: hand-made pixel art, a limited palette and retro interface elements, with magenta, purple and green over near-black backgrounds.

A compact design system in Figma defined typography, colors and reusable components, keeping the whole game consistent.
