Nice game.
The top-down cutesy-casual visuals remind me of Overcooked, which I love. Fun Disney-esque animal style and I like the Japanese setting.
The music was good and fit the environment well. Most of the SFX have a fun sound to them. I especially like the dialogue sounds. I felt there needed to be a few more foley sounds for things; the place had a lot of activity but didn't sound that active (maybe it was a lack of ambient group sounds?).
The controls took some getting used to, having a floating mouse like that felt rather weird to me. In other games that have the mouse used for both clicking and for rotating the camera, I find they tend to have the mouse hidden and in control of the camera by default, then you hold alt or tab or something to reveal it for interacting with objects. Also, it feels weird to hover over an object just to press E, left-click would be more natural.
That being said, I did get used to the controls after a bit and didn't think too much about them after that.
The gameplay was rather unique. I didn't really get it at first but got into a bit of a groove and found it quite enjoyable. Exploring the map was fun in general, as well.
Your use of the theme was well done.
I can tell you put a lot of love into the game. Overall, a great submission.
PS
I managed to get stuck behind the dressing divider in one of the rooms by the start you can enter where the camera pans to a more downward-angled view; the one furthest to the right. I went behind the divider and couldn't escape and had to restart.
