This would definitely be fun to play with a friend.
I liked your use of theme as well as since I saw the dev log on discord how it turned from a game about particles to cats and dogs.
I wish that maybe this was a more level-based game so you start just needing to herd a couple cats and then ramp up the challenge. But I also know endless style games are sometimes easier for game jams. Especially when on a dead line!
Nice use of theme and fun game.
Nice job!
