I Built My First 3D Game With AI in 1 Day

A small experiment using Pixelfork and Three.js to create a 3D game

March 10, 2026

A few weeks ago, I noticed something interesting from users of my Pomodoro timer website, Pomofox. Many people were asking the same question:

"Can we have a small game to play during break time?"

That idea stuck with me. Pomodoro breaks are short, usually around 5 minutes, and sometimes people just want something fun and quick before getting back to work. So I decided to try building a small game for it.

Trying a 3D Game for the First Time

I have built a 2D game with AI before, but I had never tried making a 3D game. I was not very familiar with things like 3D assets, file types, or how everything fits together. So I thought this would be a good experiment.

The result is a small game called Pomofox: Shadow Break.

It is a short 3D top-down action game. You play as a hooded fox and fight magical skeletons. The idea is simple: play for 1–2 minutes during your Pomodoro break, then go back to work.

Built With Pixelfork + Three.js

I built the game using Three.js, and I created it with Pixelfork, which helped me iterate quickly.

This was the first prompt I started with:

Create a 3D top-down action RPG using Three.js with a controllable character, enemies, and simple combat.

And this was the first and last version:

From there, I kept improving the game step by step. Instead of making big changes, I made many small edits.

I added things like:

character movement and combat
enemies and wave spawning
pickups like health and shield
loading screen and game over screen
sound effects and audio

Keeping the scope small really helped. It made the project feel manageable.

Finding 3D Assets

Since I'm not a 3D artist, I used some free assets from Itch.io. All of them are GLB models, which work well with Three.js.

Here are the assets I used:

Trees — https://venturon.itch.io/fir-trees-textured
Health & Shield Pickups — https://venturon.itch.io/health-magica-stamina-potions-3d-models-fbx-glb
Skeleton Enemies — https://brackeysgames.itch.io/brackeys-3d-game-tutorial-assets
Fox Character — https://gtibo.itch.io/hooded-fox

These made it much easier to get a playable game quickly.

The Goal

The goal was not to build a big game.

I just wanted something simple, quick, and fun that fits inside a Pomodoro break. A small moment of play before getting back to work.

If you try it, I'd love to hear what you think. And I'm happy to answer questions about how I built it.

You can also remix the game directly in Pixelfork and make it your own.
