4 stars: It's a fun game, got me really hooked, especially in the beginning, but after you uncover most birds and upgrades the game starts getting demotivating...I still play to have the last 2 legendary birds, but since there are no other upgrades it's not as much fun as in the beginning. I like the fact that you don't have to spend any money to progress, the add-play balance is ok if you play for free.
4 stars: This is a solid endless runner. It has a good gimmick, the art and music are fun, progress is slow but not annoyingly so, so there are a lot of hours you can sink into this game. Even though it is quite repetitive, it somehow manages to stay entertaining. There are ads and microtransactions but forced ads are few and far between and the opt in ads give fair rewards. Any microtransactions are fun but aren't mandatory. 8/10 would recommend.
3 stars: The game itself is ok, but some bits are impossible to get past. For some reason jumping over the moving cars is IMPOSSIBLE without losing most of the zombies??? And the bombs are ridiculous. Other than that, everything else is really confusing and after playing for ages I still don't understand most of it, the start tutorial was not informative. Overall quite stupid. But then again what was I expecting with a zombie tornado game
