I really like the job you did with the music and sound design and visually this was a treat to play. One suggestion though, you might want to darken what is considered in the background, I was confused on what I could actually jump on/touch because it looked the same to me.
I wasn't able to figure out how to get all the candy on the 3rd stage but that was more of a me problem. Didn't play the other stages yet because I managed to soft lock myself by falling on the edge of a fence and getting stuck.
All in all, a nice sort of platformer, you have plenty to work with if you wanted to make more stages.
