Visually, the game is very nicely done.
It would've been nice to have some audio too, to enhance the experience.
The firing could use some tweaking, as I experienced some delay between pressing space and the projectile actually firing. It was more evident when the projectile fired after I had already died and the bird sprite was gone from the screen.
I like that as a Phoenix you keep reviving endlessly XD
It would be nice for the bird to eventually find the eggs at the end of the level and maybe load a different background for the next level.
Good game!
