This game is a custom web parser built from UnityGl. It seems to work based on searching for one or more keywords in your text, ignoring extra words.
It's built around the trolley dilemma, which is an ethics puzzle: if you know someone is about to die (due to, say, a trolley crash) and you could stop it by having other people die, what would you do?
In this game, your choice on one trolley puzzle may lead to another and another and another. You have 51 possible outcomes to search for.
It was interesting, but hard to interact with.
