What they did
Octoberry highlights a solo dev with no coding or game experience who built a playable 3D game mixing Ragnarok Online and Monster Hunter in 6 weeks with Opus 5.5 and Godot.
Result (as claimed)
Custom characters, environments, VFX and shaders from a beginner.
Tools they used
Cost: Pricing depends on the tools you pick; check each official pricing page.
Set it up
Write a one-page brief
Describe the app in plain words: who it is for, the 3 core screens or actions, and what "done" looks like.
Start the project with your agent
Open Opus 5.5 and paste the brief. Ask it to propose a stack and a file plan before writing code.
Build one slice at a time
Ship the smallest working flow first, run it, then add features one by one. Commit after each working step.
Test it like a user
Click through on desktop and phone. Ask the agent to add basic tests and fix anything that breaks.
Check security and ship
Keep keys in environment variables, check auth and database rules, then deploy and share the link.
Copy the full setup prompt
Paste into your agent and it will walk you through the setup, asking before anything that sends, posts or spends.
