It's a good game. The music along with the slow changes that occur over the play-through give a slight sense of horror from knowing you'll undoubtably be next. It repeats, over and over, the same thing day in, day out, but each time something changes for the worse. It's more artistic and thought provoking than game, hence the 4 stars, but the ending was pretty clever. The game is about what you say it's about. It's a reflection on yourself, what you see the situation as. If someone was to play it and say "Oh, it's a bunch of furries getting killed, LOL", then that kinda shows you what they're thought process is.
Even I'm surprised at the conclusion I came to, that it actually lead to a serious discussion with your own psyche about what you make of a situation. For me, the game was about the stay of (literal) execution for the characters and about a man who had simply given in. For him, there was no hope, no freedom. He was already dead, just a body shambling through the last days of his life, numb to the dead and dying around him. It's a very deep psychological game, I'm honestly impressed.
Which, coming from me, is damn rare. Plenty of praise for this experiment.
