I like how your bird doesn't just die instantly but loses some of the feathers (turning white with only the inner ones remaining) first.

It's a bit unclear to me what the different kind of enemies do, is there some significance for the parachute ones or the one in the plane, or are they just having different speeds and possibly scores attached to them?

It's actually surprisingly hard to fly in formation on the "normal" game mode and not lose too many of the birds too quickly, one has to avoid the incoming enemies quite a lot...

Really fun game, the audio and visuals fit really well too. I loved the concept of having all the birds fly at once and switching between them - I did think it would be cool to maybe have a "powerup" that let them all shoot at once for a few seconds :) Other than that I don't have any suggestions for improvements, it's a great entry!

So cute!  Love the style and the bird designs.
