Very cute, and very clean, well scoped, bug-free jam game.
Suits the theme well too.
If you want to extend this, I would suggest some sort of progression system.
Like, maybe, being able to spend points to buy new toys or unlock new play areas for the kittens, or something.
It's nice as is, but after a few minutes you've seen everything, so there's not much motivation to hang around.
Also, I couldn't figure out how to quit the game using in-game controls.
I don't always expect to be able to from jam games; but I checked the Credits first, and I had to exit and re-open the application to actually play the game.
Was there a back button I missed?
It doesn't super matter, because it was worth the restart anyway.
