This was fun! Solid asset choices overall, though the music didn't really fit the theme for me, and it got old after awhile. I would at least consider changing it for different levels or zones.
It took me awhile to get the hang of jumping, I was stuck for awhile on one of the earlier levels but eventually I got the hang of it and was able to play through to the end. One major cheat bug, you could get candy from the same door multiple times if you were fast enough!
