Skyward shift

Im 17, and im intrested in becoming a software engineer. I learned C++ by myself, and made this game using sfml libraries. This game is a simple one, where the player is a plane at first, and has to collect points from incoming stars, and has the ability to shoot down birds if he takes a red ball. Read the README file after downloading to understand how the game works.  Please report any bugs or things you might like me to add to the game, but take in consideration that im still learning. Thank you!
