Despite the fact that I'm upset with the devs, this game is WAY better than Westland survival. As of right now, this is my favorite survival game on the app store. The rate that you progress is perfect. It's difficult enough to be a challenge but it doesn't take ridiculous grinding either. I have made purchases in the game but it is designed to still be great for free. There's enough to do that it never feels repetitive. I wish you could buy VIP for 7 days instead of 30. Awesome job so far.
