The game starts out so well, but becomes impossible to progress. I've made it as far as The Museum, and I think I'm just done. I am stuck replaying that first level repeatedly to try to get enough power points to go to the next level. I want to keep playing because it's fun whenever new things open up, but it's actually just become a chore to get the progression now.

Game play is good for an idle game. Would like to see an auto complete option instead of having to play same levels over and over. Also, the game gets stuck 50% of the time when expedition is complete and heading back to camp. Finally, I see my character just stand there sometimes, not even shooting when zombies are in range. (All via mobile and 4 different wifi connections.) Otherwise, it keeps me busy during my down time.

I love the art and game play. But the fact that ads automatically start every couple of minutes is so disruptive, they want to force you to buy the no ads version. While I understand the need for ad revenue, this took it way too far. DO NOT INSTALL!
