DeadLock OS

Deadlock OS is a puzzle game played entirely through a Linux command line. Read system logs to work out what happened, chase down permission errors, inspect running processes, and get around network restrictions. Every puzzle is a small investigation. Nothing tells you the answer, but everything you need is somewhere in the filesystem.

The commands are real: ls, cat, grep, ps, chmod, netstat. If you know your way around a shell, you already know how to play. If you don't, the early puzzles teach you, and you'll finish knowing skills that work on a real computer.

Features:

- Puzzles solved with real Linux commands

- Investigate logs, file permissions, processes and network restrictions

- Difficulty ramps up from "first time in a terminal" to seasoned sysadmin

- Learn practical command-line skills while you play

This is an alpha demo, so more puzzles are on the way. Your feedback on where you got stuck or which puzzle felt unfair is very welcome!

- Keyboard: type commands into the terminal
