Inspiration
I had never created a game before this project. I had never used a game engine, written game code, or even heard of Godot.
I was already using Codex to build a client portal for my e-commerce profession, and I was impressed by how quickly it could turn ideas into working software. That made me wonder: could someone with no game-development experience simply describe a game and have Codex build it?
To test that idea, I created The Hardest Game Ever Created, a comedy first-person shooter built around one intentionally ridiculous premise.
The game presents itself as an epic, dangerous, nearly impossible military campaign. It includes five difficulty levels, dramatic warnings, suspenseful music, a 3D combat chamber, achievements, statistics, credits, sound effects, and Easter eggs.
The actual campaign consists of shooting one stationary target.
Winning takes only a few seconds. Losing is harder than winning.
What it does
The player begins at an exaggerated military-style title screen and selects from five difficulty settings. Every difficulty secretly launches the same campaign.
After accepting a dramatic warning and loading into the final combat chamber, the player receives one objective:
Shoot the target.
One successful shot completes the entire game and triggers an absurdly excessive victory celebration.
The game also includes:
- First-person movement and aiming
- A visible weapon with recoil and muzzle effects
- Custom title, gameplay, victory, death, and credits music
- Realistic gunshot audio
- Achievements and statistics
- Local save data
- A complete credits sequence
- Alternate failure behavior
- Comedy Easter eggs
- A standalone Windows build
One Easter egg provides the only reliable way to lose. A poster explicitly tells the player not to shoot it. Shooting it produces a special death screen. In this game, following instructions makes victory almost guaranteed.
How I built it
I built the project using GPT-5.6, Codex, Godot 4.7.1, and GDScript.
GPT-5.6 helped me:
- Develop the original premise
- Structure the comedy and game flow
- Translate creative ideas into detailed technical instructions
- Analyze gameplay screenshots
- Diagnose visual and interface problems
- Plan menus, achievements, statistics, credits, audio, and Easter eggs
- Communicate precise revisions to Codex
Codex handled the implementation inside Godot. It created and revised the project files, gameplay systems, menus, first-person controls, weapon behavior, target interactions, achievements, saving, audio integration, credits, Easter eggs, and Windows export.
I also used ElevenLabs to create custom music and sound effects, then gave those audio files to Codex to integrate into the Godot project.
The project went from an idea to a functioning game in approximately 12 hours.
Challenges
The largest challenge was that I had no previous game-development experience. I did not understand Godot scenes, GDScript, nodes, signals, rendering methods, export templates, or how a Windows game is packaged.
The first version was functional but highly experimental. The weapon placement needed repeated visual adjustments. Some environmental text appeared to float instead of looking attached to walls. Audio needed to be replaced and configured so certain tracks played once instead of looping.
The standalone Windows export also initially froze while the music continued playing. This required additional testing outside the Godot editor, command-line logging, renderer comparisons, and debugging by Codex before the exported version worked correctly.
Each problem required me to describe what I saw in ordinary language, work with GPT-5.6 to turn that observation into a technical instruction, and then have Codex implement and test the correction.
What I learned
The most important thing I learned is that creating software no longer has to begin with knowing how to write every line of code.
I still cannot personally explain most of the GDScript behind this game. However, I learned how to direct development, test behavior, recognize problems, provide useful feedback, work with a game engine, manage assets, integrate audio, and export a standalone application.
This project demonstrated a new creative workflow:
- A person describes the experience they want.
- GPT-5.6 helps refine the vision and convert it into precise instructions.
- Codex builds, tests, and revises the software.
- The person remains responsible for the creative decisions, humor, testing, and final result.
What is next
This project began as a small experiment, but it changed how I think about games.
Instead of waiting for a developer to create something I might enjoy, I can now imagine designing a game specifically around the stories, mechanics, and humor I want to experience.
The next step is to use what I learned here to create a larger original campaign with multiple levels, enemies, secret areas, collectibles, upgrades, and a complete story.
The Hardest Game Ever Created took approximately 12 hours to build and only a few seconds to beat.
