The app could benefit from a clearer display of timers, as sometimes it's hard to track how much time I have left. I’ve noticed that my data usage goes up significantly when playing, which is something to keep in mind. The gameplay feels fair, and I have never felt cheated, which is always a plus. I like that the app allows me to replay tutorials whenever I want; it helps refresh my memory on various strategies. Connectivity issues have cropped up now and then, causing random disconnections that break my concentration.
