The visual style stands out. It's really pleasing to the eye.
There are some excellent aspects in terms of immersion, particularly with the internal dialogues of other passers-by.
The music is great, and the B theme of the main music is catchy!
The level design is sometimes restrictive. The barriers are not always very clear, and I couldn't always find the opening. There are a few “objects” or “points of interest” missing to guide the player in the right direction. Notably at the end, when you see the cat for the second time, the arrow points to the bottom left, but you have to continue all the way to the right to reach the end. Perhaps you could add some markers, plants, or other eye-catching features to encourage players to go in that direction.
Otherwise, the ending cutscene is very poetic. Well done on your game, I had a great time playing it.
