I really like the visual style, it's simple but very satisfying. The gameplay is really fun but I think it could be improved if you decreased the bullet speed. Since the player ends up pretty close to the enemies in this game, having the bullets move so fast makes it extremely hard to even react to them a lot of the time. Many times I got hit by something I didn't even see, and a lot of the levels I got through just by dumb luck instead of actually trying to dodge bullets. But still, fun gameplay and the difficulty on most of it is perfect. Solid use of the theme as well. Nice job!
