Cute little game! My only real critique is how the character jitters if you press up or down against a wall - if you press down against a wall while the camera is moving, the character even starts jittering to the sides!
It'd also have been nice to have some kind of ending, or a highscore to keep track of, but it's quite a simple yet nice little romp as-is. I like how the start of each level makes sure you know what you need before letting you progress.
