Simulator capture at the app's native 320x240 display resolution:
How to use it
Choose a mode with Left/Right and press Select. Drive with Left/Right, then Select to aim. Left/Right changes angle, Up/Down changes power, and Select throws. Back returns from aiming to driving; Menu pauses. The first player to reach 100% soak loses. Hitting a butterfly directly activates a hairdryer that removes 25 soak points.
Badge vs Badge requires two badges with
badgeware.linkfirmware. Both players choose that mode, bring the badges close, and confirm with Select. The simulator cannot verify the radio.Licensing and intellectual property

Additional notes
Validation performed:
python3 .github/skills/hyb26-skill/scripts/validate_app.py badge/apps/pig_vs_goose— passed, zero warnings.python3 .github/scripts/validate_app_readmes.py badge/apps— passed.python3 -m unittest discover -s tests -p 'test_pig_vs_goose*.py'— exited with status 5 because no matching tests exist; this is not a test pass. The README no longer advertises these absent tests.check_app— passed, no errors or warnings.run_script— exercised computer mode, aiming/throwing, the computer's following turn, pause/title navigation, pass-and-play, simulated rotation, and the link-search lobby without a traceback.record— captured the hairdryer animation and asserted that it reduced soak from 70% to 45%.No physical badge deployment or on-hardware checks were performed. Two-badge pairing, radio delivery/retries, disconnects, shared pause, rematches, and the menu icon still require real hardware verification. Licensing checkboxes are left for the contributor's explicit attestation.
