can Opus 5.5 actually help build a video game?

i wanted to find out.

so i turned an idea into a real game development project.

the process:

→ 1 idea
→ 1 AI coding partner
→ multiple gameplay systems
→ endless testing and iteration
the goal wasn't to generate a cool screenshot.
it was to make the mechanics work.
because there's a huge difference between code that looks correct…

and a game that actually feels good to play.

Opus 5.5 helped me work through the development process, but every mechanic still had to prove itself in-game.

here's the result.

what would YOU build with an AI coding partner?
