Thank you all for the feedback! It is very useful. I can totally agree that the birds are blending in with the background and I should work on changing the colors around to make them more noticeable and easy to avoid. I also agree that the level of difficulty on the second level could be simplified since it is much harder than the first level. Overall length of the game could be increased too. I am very happy that my sprites design got a positive feedback since I put a lot of time into them. Overall very good feedback received and it will help me with my future games!
