Love the music, total bop!

The gameplay kind of reminded me of Space Monkey, where you have to turn to catch and avoid objects coming at you.

I thought it was interesting that the birds changed size as they came closer to you. I wonder if that could have been made into a more clear mechanic, like maybe there are different types of birds that grow and shrink as they get closer.

I think this is great shell to add mechanics on top of, good job!
