The end product just makes the pass mark, however the code quality is very low and outdated. The PHP version of the backend is old, many functions are deprecated and doesn't work out of the box - it required about an hour bug fixing and updating.
The Unity project is quite old too, written in 2017 version, and there are some minor design issues, but to be fair these issues did exist in the demo too.
The concept is a good idea, but the end product can only be used as a template at best.
