You're trying to open the game directly from your file system.
ES6 modules (used in this refactored version) require a web server due to browser security restrictions.

Option 1: Python (Easiest)
cd ~/Sites/honey-harvest/bee-game python3 serve.py

cd ~/Sites/honey-harvest/bee-game python3 -m http.server 8000
