This is one of the early choice of games.
The plot isn't about an "end of the world" scenario, but mostly an urban fantasy mystery with a certain superpower. Time manipulation.
The protagonist gets this power and must use it wisely, for the villain of the story depends on it being uesed!
It's not too wordy, and not too short, just enough for a playthrough, and yet the magic of the first choice of games courses through it.
