Read the game's source files to understand:

• src/scenes/GameScene.js — find death/failure methods to patch out

• src/core/EventBus.js — event flow

• src/core/Constants.js — input keys, game dimensions

• src/main.js — verify __GAME__ and __GAME_STATE__ globals are exposed

Create scripts/capture-promo.mjs adapted for this specific game:

• Patch out ALL death/failure code paths

• Generate input sequences matching the game's actual controls

• Include entrance animation pause (1-2s)

• Default viewport: 1080 × 1920 (9:16 mobile portrait)

• Default duration: 13s game-time

3. Copy the conversion script

cp <plugin-root>/skills/promo-video/scripts/convert-highfps.sh <project-dir>/scripts/

chmod +x <project-dir>/scripts/convert-highfps.sh

4. Run the capture

mkdir -p output

node scripts/capture-promo.mjs --port <port>

bash scripts/convert-highfps.sh output/promo-raw.webm output/promo.mp4 0.5

5. Verify and preview

Extract a thumbnail at the 5-second mark and show it to the user:

ffmpeg -y -ss 5 -i output/promo.mp4 -frames:v 1 -update 1 output/promo-thumbnail.jpg

Read the thumbnail image and display it. Report duration, frame rate, and file size.
