Can one fact
destroy the truth?

Virtual space/game as a visualisation of the coherence theory of truth. Things make sense when they are internally coherent. If some new fact is added to the coherent set of propositions, the set stays coherent only if all the facts remain harmonious with each other and don't create any contradictions. In the game you can experience how does it feel to be a fact that is coming into such a coherent set of propositions.
