How I had Claude create a game that can be played using a single button? - CLUB NIGHT

I have MATLAB R2026b, the MATLAB Agentic Toolkit, and Claude Code installed.
In the first session, I asked Claude (Opus 5.5, High effort) to review the game rules, suggest MATLAB Agentic Toolkit skills, install them inside the project folder, and create a CLAUDE.md file.
In the second session, I asked Claude to create a combat game in which the player controls a simple stick figure wielding a club; clicking makes the figure swing the club. Simple monsters approach the player and drain the player’s health on contact, while hitting a monster with the club eliminates it. The game has an old-school 2D look, with a dark blue, star-filled background and light blue characters.
That's it. You can see result here: CLUB NIGHT
My best score until now is 2060.
Let me know your best score in the comments.
CLUB NIGHT - GAME OVER

Hi Jan. It's interesting to learn that you ask Claude code to review the rules, suggest skills and create claude.md file. We have the agent.md file in the starter kit. Maybe it's not clear in our instructions.
I like your game. How many iterations with Calude Code did you have to get there?

Eight iterations in the first session. In the second session only two: /init and the prompt I shared here. My claude.md was created for the efficiency of the second session.

Thanks for sharing what you did to create the game. I felt rising tensions as the monsters increased and I liked the variety.
