Given the comments, I think this is probably the most relevant quote from the project creator (my bolds):

This project was built with AI, and that is part of the point.

I am not a reverse engineer or a security engineer, and I did not come up through whatever field normally teaches this. Almost all of the code here was written by AI coding agents (Claude) that I direct: I decide what to try, think up the angle of attack or the workaround, and the AI implements it quickly and comes back with a result I can check. That loop (an idea, an implementation within the hour, a measurement that says whether it held) is what made a project of this size possible for one person.

What I take from it: the bar for entry has dropped a great deal. The creativity is still yours (which problem to solve, which trick might get around it, when a result is not good enough), but the distance between having the idea and seeing whether it works is now very short.

Two rules kept it honest: every claim has to come from a test or a measurement (this README says what was measured and what was not), and nothing derived from the game goes into the repository. It is a study project; expect rough edges, and mistakes that a specialist would not have made.
