This is my own video game, Fly Bye Birdie, available for iOS and Android. It started with a few sketches of some cartoon birds and grew from there. Although Unity3D was used, the game is a 2D mobile platformer. Adobe Photoshop, Animate, Audition and my whistling were used to bring this idea to life and to mobile.
