Hi,
I've tried your game and here's what I think about it:
- The flying mechanic is very cool and I've never seen it before, good job on that!
- Having the chicken turn into an egg after a while is also a great idea, because of all the possibilities you receive from that.
- The sound effects are well done!
- Try to play-test the game with the player in mind before releasing it: I'm stuck on the second level and I've tried about 50 times to nail it. This could scare away potential players when they're playing your game.
- Some visuals like a nest and a chicken would top the game of, but maybe that isn't the style you're going for.
I hope you can do something with my feedback :)
