At first I thought that it's another idle builder game. Never have I been so wrong!
I was really surprised when I failed the first time. Unlike similar games, this one does require some careful planning.
It looks and feels and plays great and well-polished. I am trully amazed how you managed to develop all of it in 48 hours. Really well done!
On the improvement side though, it seemed rather slow, Control button for cancelling was a bit inconvenient and some general instructions and descriptions of buildings would help.
