Well done dude! This is one heck of a solo dev submission! The bird is cute, the background graphics, and the sound effects are pleasing to the ears. My only (minor) gripes is that the wall jump mechanics are a little hard to time perfectly and the camera is a little erratic at times.
Oh and did I mention that I loved the lyrics? They bring a tear to your eye but fill you with pride. They are insightful and thought-provoking. They truly speak for themselves when they say, "Birdmo."
