I appreciate the variety in the clouds (differing opacities & speeds). In just 3 days, you've established a decent art direction for the rest of the game to built upon. I also like how some pigeons sort of dive from the top and are more difficult to hit, while others flock together and can be taken out together. I can tell a lot of time went into the visuals of the game, which explains lack of a high score or timer. I developed my game in 2 or 3 days as well, so it's nice to see that you accomplished something so polished for the time you had to work on it.
