As a game, The light in the darkness is very poor, it is slow paced, has poor controls, no voice acting and is overall not a very fun experience.
But it is obvious that the intention of this game was to provide a history lesson to players. I applaud them for this, however this is a video game, and I have provided it with a rating that I believe to be fair.
In conclusion, I do recommend this game especially you are uneducated on the history of this subject, but as a gaming experience it is very lacking.
