A Dark Room

Not quite IF as I imagine it, but hey, it's text, it's a game (of sorts) and I can assure you it does not take long to get fully immersed in this simulation of a society developing.

It is amazing what sparse text and a few action buttons (with reload-timer) combined with human imagination and empathy will do to suck you into this world, how little of a nudge a brain needs to be there in that other world.
