A diverting little game, that with more work, could be great.
It is obvious that the writer has knowledge of the subject matter and it is certainly an unusual subject for a game, but it is a little too sweeping for my personal taste. Years can go by in one paragraph and I lost any connection with the protagonist because of it.
With a shorter timeframe, i.e. the first few weeks of the Nazi occupation, and micro-management of the situation "you hear footsteps coming up the stairs, do you hide under the bed, or in the closet?" it could be a gripping game.
