I love the particle effect on poisons and doors that some animations give the player visual interaction and engagement while playing. I like the mouse animation in idle state and active state. the mouse keeps moving in idle, I thought, represents saliva active moment?! XD lol while the player consciously unconsciously figuring out which food and direction to get. then the mouse turns into an open state dashing towards food, feeling like saying "I NEED THAT FOOD!" I like how you set up the obstacles on the player's way to food that naturally give the player a feeling of accomplishment
