To be honest, I love the fact that you made the enemy the carrots, I have never thought of it that way! The art was cute and beautiful(although I'd prefer for the player and enemy to be a bit bigger). The control and goal was clear as well.
I had a fun time playing your game. However, there were some problems that I had during my playtime, especially the enemy spawn locations in combination with their continuous arena-wide range to shoot at the player. This makes playing the game feels like you're supposed to bunker in a corner and take a peek to shoot a few bullets each time, especially frustrating with the player's slow movement. I don't know if that's intended or not. Another problem is that while I absolutely love the UI bar that is in the terrain, it is kinda hard to track when you have to be in the open when enemies are shooting at you from everywhere.
For me, that was definitely the biggest drawback. Besides that, there were some minor bugs such as having a wall between you and the running carrots making them getting stuck(maybe you can use navigate 2D for this?) and the player control drifting once for me. I also think that maybe you could have add more juice into your game by adding effects, upping the volume of your shooting sound effect and add a bit more screen shake when the player shoot.
