I liked the premise a lot (even though gravity for cats was never real to begin with) and I also liked the attention to detail, like the cat looking down when it falls. The levels are also pretty well designed, but feel infuriating to play trough because of the slidy gravity switch. I would suggest adding some sort of checkpoint between particularly tricky jumps, like the one at the beginning of the third level, which would really make the entire game more enjoyable since, again, I can see the levels were designed with care to explore the moveset of the cat. Also, the music is good, but a bit too repetitive, I would suggest adding a bit more variation in the future, but I know that time is limited in a jam, so it doesn't really matter if you can't spend too much time on the music, it's leagues better than not having music at all. Overall, you did a good job.
