I like the take on the theme, however, the lack of music makes the game feel a little empty. Also, after some time, the character can move out of bounds, and sometimes, the bullets collided with the wall and sometimes they just phased through it. I think you could have made the bullets shoot automatically and we just had to aim because there is no point in leaving the left mouse button. If you wanted the shooting to be manual, you could have added some type of ammo or maybe reload system, but i can see that that would be a bit overscoped. Overall, I like the game, the spirals are hypnotising
