I got a few days in, but I'm not fast enough reacting to play the minigame properly - in fact, it seemed really out of place. I'd like to play again just to see what happened to the family, but I know I won't be able to progress very far.
I really want to know what happens to the mother and son, though. On the whole, this has a very Papers Please vibe to it. If you feel like developing this into a larger game, I'd be up for playing that one too.
Also, you should probably know about the poppy reference, poppies weren't a popular war symbol until after WWI.
