Interesting concept! I can't really provide much feedback since the game isn't fully functional, but you may want to consider uploading the game to a hosting service like Netlify or Vercel if your game needs to communicate with an external API. These services offer free hosting and allow you to configure the headers.
Other than that, incorporating ChatGPT is a pretty cool way to make the experience unique to each player. You may want to consider putting more effort into the landing page. Adding the screenshots you posted here on the game's page seems like a great way to encourage players to check out your game as well as adding a background image. Overall, good job!
