Doublespeak Games in 2013 released an open-source, text-based role-playing game for web browsers called A Dark Room.

Gameplay starts out innocently enough with the user awakening in a dark room and having to tend a fire.

Soon enough, you’re enveloped in what eventually became a runaway success for Android and iOS devices.

And now thanks to this portable app, you’re free to dive in on virtually any computer.
