Show HN: I built a simulation game to practice online self-defense

I built Tekushi because I felt that most online safety training are outdated and boring.

I wanted to treat digital safety like a martial art—something you build through repetition and muscle memory.

This is a browser-based simulation game where you practice detecting phishing threats and dark patterns in a safe environment.

You can try the first modules without signing up. I built it as a solo maker in Python.

Feedback request: Does the 'gamified' approach feel effective to you, or too gimmicky? Is the difficulty level appropriate? Thanks!
