Good music, good choice of assets. Excellent first game. This is the same genre that I started with too, as it's a nice way to learn how collisions work in godot.
I don't fully understand the concept of the game, as there are carrots AND a maze (though there is nothing to stop the player escaping out the entry). Does the player need to collect everything or just make it to the end? This isn't communicated to the player clearly, as there is no counter for how many carrots you have collected.
Is the game about finding the path between all the carrots in the allotted time? Going blind around the maze with a quick timer, which kills you does not make the game very accessible to new players. I suggest making the timer a bit longer (or remove it/only include it in a higher difficulty level) or have some sort of hint system to guide the newer players.
