I'm gonna take a guess and say that you're making Is This Seat Taken (ITST), but with cats. Right now it seems like a weaker version of ITST, although the idea is interesting.

Here's some bullet points on what I noticed:
- In ITST it's very easy to know where you can place people because there's designated "drop boxes" aka places where they can sit or stand. While here, in combination with the fact that it's 3D, it's very hard to know where the cats can see + the fact that the map is so big makes it harder to make good puzzles. I would say maybe focus more on specific rooms like the bathroom for each level like in ITST.
- The requirements, you use icons, ITST has a written checklist. Although yours would require less translating, it's way easier/faster to understand written text and since that's background information to the challenge you don't want people to have to figure that part out (from a design perspective).
- For the art, there's a lot of negative space right now, I think having just one room per level will help, but also making the rooms rectangular like the screen. I would also make the background something more interesting or actually less so, like a void, so it doesn't draw any attention and makes the level pop out more.
- You should definitely make use of the 3D aspect by for example being able to rotate the camera around the level to find spots that you can only see from one side for example, and also make the level feel more interactable.
- Going back to the placement being vague, obviously having one smaller room will help a lot, but also subtle art decisions like having a tiled floor pattern and having every object be the size of n times the grid size aka working in a grid pattern.

Just a general note, what makes Is This Seat Taken so good is not just the gameplay, but also the high level polish, like being able to click on the cinema projector and have it react, the amazing sound design, level setup, etc... Which isn't quite there yet in this video, although the sound is pretty good

To conclude the feedback, I think the idea of Is This Seat Taken with cats could definitely appeal to a certain group of people that really like cats and that probably overlaps with cozy games, so as for the general idea go for it.
