Personally I loved the art of the game, especially with the animation. The tone was great and the art did well to stick to it. The action of having to pick up carrots was very good as well since you have to actually interact more than just walk by and automatically attract, ect... However, I found that the theme didnt really have that much impact here.
Besides that, i think your core gameplay is interesting but it is lacking some sides. For that, I think you should create a difficulty ramp for it by using a timer and spawn. I also think that you should check the hitbox of the enemies again bc even though for the most time it was ok for me, there was this one specific guy that i took 10 shots to kill(probably bc of angle) Besides that i think you should also add a range for your spawn points so that the sprites dont overlap. Finally I think you should make the animation faster and the bullets bigger to make it jucier, while setting the bullet's spawn point at the top of the gun nozzle in the animation player instead.
But all in all, it was a fun game.
Edit: oh also in my opinion, dont scroll the level too fast bc it made the eyes tired after a while
