You are right; there was an error in the description. The issue doesn't stem from Google but from Ren'Py, which imposes a 2 GB limit on compiled APKs. That is why Ren'Py games exceeding this limit (like my previous one) use a lightweight APK containing only the script files and some UI elements, alongside an external file that holds the heavy assets.

Although this isn't explicitly explained in the documentation, it likely stems from the build process—specifically the use of 32-bit tools like Gradle—which causes this limitation.
