I built a game called CHRONOS II. You play from a deck that stays with you as you move from machine to machine. It keeps track of the systems you control, the tools you've found, and the fragments you've recovered. The terminal in the middle belongs to whatever machine you're currently inside.
Something walked out of an air-gapped vault, and you're chasing it. The thing absorbs people. They're still conscious inside it. The most recent ones are still partly themselves. Sometimes they can reach you and help.
Every level is drawn from something that actually happened: Mirai, the Bangladesh Bank SWIFT heist, SS7, Moonlight Maze, the Ukraine power-grid attack, Stuxnet, and a Cold War satellite.
Best on a desktop with a keyboard, but it runs on a phone.
Solo dev. I'm especially curious what people here think of the atmosphere and story, not just the puzzles.
