The game looks incredible, nice job! The music, though quiet, was nice to listen to. The gameplay is basic but executed nicely.
The main issue I have is the player position in regards to the camera, the player character is too far left on the screen for the gameplay to feel natural or good. By either moving the character more to the right or the camera to the left, the gameplay can be so muc better. Also the player character sprite looks a bit out of place to the rest of the game. I think you forgot to turn off certain properties of the sprite when importing it into unity (Filter Mode: Point, Compression: None).
Otherwise, a very nice, good looking game!
