Very very nice! Your art style is so fun and charming, extra points for that. Also love the 2.5d thing going on, it adds some fun character and depth to the game. Your music is also good, not annoying to listen to, just a nice simple jam that adds the tension you mentioned in the GDD without missing the humour of the game.
My critiques, which I don't rate on:
The main character and her cats vibrate as you move forward and back- I wonder if this is because the character movement is horizontal but the angle of the floor is not perfectly horizontal?
Sometimes when I threw a cat, the cat sprite attacking the enemy would not appear, making the enemy look like they're just running away and collapsing ahaha.
I could see inside the building when i jumped on the balcony outside the front door.
This one affected play: the angle of the cat throw meant the sometimes I would miss enemies at a certain distance away from me. I would recommend reducing the curve of that parabola, but the distance felt right.
