This was a fun little game. Some suggestions I would say, making the incoming projectiles unable to be shot from the air would give the player more urgency to move around. Until it ramped up I was in no danger as long as I got in position above the incoming enemy. Good starting point for a game though.
Your scene changes or camera movement wasn't working properly. I got caught at a point where the player was off screen but I couldn't see them, and I couldn't get back in scene. Overall cool idea though.
