Game is good. Ads are really bothersome (-1 star) but the remove ads purchase is very fair and a one time purchase. I really enjoy the game but it needs new content and QoL features (-1 star, can be earned with new content). It's obvious there was plans for new buildings and zombie types, I'd love for a tank or speedy or even some sort of support zombie type to use. Maybe have the zombies hounds be manually spawn able as well. For quality of life, please add a button to mass open chests.

No mandatory ads is good. Privacy policy states no data is shared but the data collection is slightly worrisome. I'm only level 4 and the game so far seems good, the levels seem a good length. I wouldn't necessarily mind a mandatory ad between the levels since the levels last around 10 minute if it improved content and bug fixes. Overall 4/5 nothing bad about the game, just the data collection might worry some people and some lightly expanded content wouldn't hurt.
