Lossy Inc: The Game
A Sierra-style point-and-click adventure. You're the new security hire at a company leaking secrets everywhere: an AI coding agent, a forgotten NAS, a contractor's old key. Use GitGuardian to find out what's real, who uses it, and how to fix it without breaking anything.

Don't Break Prod
Lossy's friendlier sibling. Start with almost no access, then win people over one floor at a time to rotate a live payment key at 11 PM, with GitGuardian as your evidence, and without taking checkout down. Lost pens and rubber ducks included.

The Little Key
A production database key is born, 528 bytes and eager to help. It never knows it gets copied, into a text file, team chat, the wiki, an AI chat, a public repo. You follow each copy until its system is finally wiped, and collect every key's ring.

Learning Jeopardy!
