Hey,
This game feels great! The camera shake implemented in the game is really a plus factor making this game super impactful, however, it also seems like you have overdone this same thing too. Another thing is the obstacle pacing, the obstacle is traveling at a very slow pace making the player difficult to traverse in the vertical direction as it's colliding most of the time with the asteroids. Further, you can add up various elements in this game to make this super interesting to play, like for example, powerups, abilities, obstacle variation, etc.
