5 stars: Fun survival game with lots of options for upgrades and unlockables. A big plus is the ads are not invasive.

4 stars: This game is pretty well balanced, the bottlenecks don't happen often(or at all) if you do the right choices and keep upgrading. The ads are not invasive and never make me lose interest.
