This was really fun.
Great:
I liked how the crops slowly disappeared as the health went down, it felt like the stakes were really real.
I also liked how there were different birds, I'm guessing they do more damage, that part was a bit unclear though.
The landing page + branding is really polished
I like that you start outside of the gate so it teaches you to move
How close you need to be to tap the birds was really well balanced
Improvements:
Would be good to have a way to win as it gets a bit tiring after a bit.
The music add urgency but feels like it doesn't quite fit the art style, this is purely taste though, in general it's good and getting you moving
Experience:
Overall this was really polished, intuitive and fun. I like hearing the bird calls and watching them while also going and protecting my crop.
