Suprisingly fun game. Trying to stay without depth at the end of month was thrilling to watch. Game was ballanced for this, but for someone who never played the game before it was quite hard figuring out the perfect strategy, because game starts quite hard right away. But once I had some strategy to stay without depth it was fun.
Edit:
I also liked how you get upgrade when staying in depth at the end of month, ot ballances the game and makes risking important.
