Time travel stories can have pretty high stakes, because usually you only travel in time when you really need to change something. A killer robot is trying to kill a lady because of something her son will eventually do, that kind of thing. My favourite episodes of Doctor Who, by contrast, were always the ones where the Doctor met a miserable dog-alien thousands of years in the future, and the dog alien is like "Not only is the planet about to blow, but my marriage is in trouble," and then the episode was mostly about the latter issue rather than the former. This is all by way of introduction to Eternal Threads, a puzzle game where you go back in time to stop everyone in a house share dying in a fire.
To save a present that has been rendered apocalyptic by time travel itself, you are part of a team who go back and change tiny things in the past to fix it, in this case 2015. While it is imperative for some reason that the fire does indeed happen, it is just as important that all six occupants live. You can alter small decisions they make in the week running up to the fire, and so save their lives by choosing whether they go to the pub, if they comfort each other in times of need, or what they have arguments about. The beat of a butterfly's wing, indeed.
