Thanks for the fun game! here are some thought I have when I play the game:
1. The tutorial didn't expain this is a turn-based game at the begining. In addition, the "next turn" button is so perfect for "tutorial next page". I only understand how this game actually work when I am reading tutorial part 3.
2. The resource collection animation is slow, and it would get slower as the animation process. It is a pain if you have more than a hundred of resource. In the late game when I have 1000+ square to collect, I can only go to next turn and let the animations kepp flooding on my screen.
