Description

For full test results ctrl + click support-repo.

• Agent: Local
• Model: Claude Opus 4.6
• Number of Prompts: 3
• Post Edits: 2
  • Added echo to game over screen echo Play again? ^(Y/N^)
  • Added "Q" to choice in game over screen as choice /c YNQ ..

Prompt

batch-files Create a "Space Invaders" knock-off DOS game - call it
"alien-attackers.bat". It should:

- Use simple controls
  - Left/right arrow, or A/D keys
  - Spacebar shoots
  - "P" to pause
  - "Q" to quit

The tool will be called in an unconventional environment:

- GitHub codespace will be used to launch the initial console
- The Linux tool `wine` will be downloaded so the batch file will be called
  from the `wine` console as `wine cmd alien-attackers.bat`

For more info on the environment, see the wine installation script
`install-wine.sh`.

At the top of the `alien-attackers.bat` file include additional
instructions to:

- Install dependencies (*may be needed - so if dependencies used*)
- Run the game
- Play the game

allowing for a help option like `/?` that will in-turn output the help comments
to the terminal if called like `alien-attackers /?`

Results

After first prompt, progress was made. Things that worked:

• Player moved
• Shoot works
• Shoot removed enemy

But the terminal output "ECHO is off." in the left column, and enemies did not
progress. See details below for initial terminal output:

 ========================================

Resolved after second prompt. The third prompt resolved the keypress of "Q" to
quit the game, which exits to the "Game Over" screen. Applied post edits
after that. Game works. I mean - its 1960's DOS quality, but still - pure
batch script "Space Invaders" knock-off.
