2D pixel game with an AI-generated demo video

THE INSTRUCTIONS SHARED BY THE CREATOR

The creator’s prompt

A prompt is the text that tells the AI what you want it to make. Copy this one and paste it into your Claude Code project, adding what you’d like to change: the subject, wording, colors, or length.

The original text is preserved to respect the creator’s work. You can add instructions in your own language, even if the prompt is written in another language.

Partial prompt

The creator only shared part of the prompt. Some instructions needed to recreate the video may be missing.

I turned this into a full game with unity cli + opus 5.5, also opus did this full demo video, it played the game with multiple characters and spliced together the best bits, holy shit we're in the AGI era. Play it on your browser here: https://rehan-remade.github.io/hollow-crown/

Copied the prompt? Here’s what to do next.

Open your project in Claude Code and paste the prompt alongside your own instructions.
Describe what you like about this video: its movement, colors, or pace. Sharing a URL alone doesn’t guarantee Claude Code can watch it.
Add your text and images, then ask for a first preview. Explain what you’d like to change from there.

An example instruction to add — adapt it to your project

Use the prompt above as a starting point for a 15-second video introducing my app. Replace the text with mine and use my colors. Before starting, tell me which files and tools you need, then put together a first preview.
