Quite a cute game and the visual like Forever said was amazing :) The SFX on the cat was cure as well and I liked the timer moving the gravity. Not the mechanic a lot of people use, so you could have something unique here. I would recommend working on this and making it longer and more levels and puzzles.
I found out that behaviour on infinitely jumping while against a wall, if that is not intended it should be quite a simple fix, to just check if Jumping then don't jump again or something like that :)
