The game is simple and cool, the character and monsters work well visually. (although the corn projectile & explosion do not fit the art style). Having a different sprite for the enemy bullet carrots, your own bullet carrots and the ammo carrot would be nice to avoid confusions at the start (even though it's pretty obvious, it does make the game look unpolished). I wish the camera was less zoomed in. It also seems that ammo disappears as soon as it's offscreen, which can be a problem when you think you'll leave it for later or such. If you want the resource management to go this way, it might be better to give a limited lifetime to each ammo, shown by it starting to blink of fade over time.
