Very good for your first game, thought it was a cute game! A small point of feedback would be the placements of the books, because a lot of time I bounced against them and fall all the way down again  (╥﹏╥)

Too unrealistic, the cat didn't push all the books down from the shelves! ;)
Love all the sprites and the crazy fast jump/gravity, with the very fitting jump sound effect. Gameplay is simple, but that is to be expected for a 3 day jam. The win screen was totally worth the fight.

Super cute game - you made a lot yourself for a first jam game, congratulations!

I love cats, they are so cute. 
Maybe turn down the gravity, by like, 5x, it'd make the falling and platforming feel nicer. though it's a fun little game, nice job! 

Also, the winscreen was SO WORTH IT- super cute!!!
