as someone who made a platformer game for this game jam i would say that this is the best platformer game in this game jam. may be one of the best i have ever played personally? i like it more than mario at least.
with that being said, ill say what i like and give feedback on some stuff. (i dont have much feedback your game is good mostly, it will be nitpicky and potentially personal preferences.)
the art style is amazing! the cat especially is very cute but the whole foreground and terrain is very cute and looks almost fluffy. the background looks very wavy and in theme, it looks almost abstract like i can dream it to be whatever i want. this whole world looks kinda like a dreamy wonderland to me and i love it!
the music is very good! i dont have any complaints at all regarding that, its calm and makes me feel cozy like im hugging a cute cat!
the platforming is simple at first and gets harder as the game goes on and i really like that!
onto feedback, i dont have much to be honest. some areas i felt myself have to stop which i didnt like very much, thats personal preference but it felt better when i was constantly moving.
i think more sound effects could be good, like maybe a walking sound effect or a sound for the enemies.
i also think maybe more enemies could've been good, but it seems you did run out of time unfortunately.
overall this is an AMAZING game! you're an amazing developer too for making this game! good job!
