Great game, I love card games but never played something like this, despite how it could look in the beginning the game gets really intense, as you need to balance your well being, the moral implications of your actions and the distance from the sand. Perfect for a lot of replayability, the user interface is also really well crafted.
The dreams sequences between each day are also really interesting and spooky, I normally make suggestions in my reviews but I believe this game is perfect as it is, obviously the only problem is that is not more like this to keep playing.
One of the other comments mentioned you should add more cards but I believe having limited resources and options is part of the narrative of the game and it fits perfectly.
Once again, great game!
