How to properly deploy app without paying for Google Cloud?

I am building a web game inside AI Studio, using Gemini 3. It’s using React

I uploaded my project to github and used Vercel to deploy it. On Vercel I connected the Github repository and deployed the app, but after all is said and done I am just getting a blank solid color screen when I open the link with the game. Same thing happens if I download the app from AI studio and open index.html - just a blank, solid colored screen.

All the files should have been uploaded to github and/or downloaded locally, so things should be working correctly, but they are not. Not sure what the deal is? Thank you.
