I like the idea and i think its a very good first gamejam game and when it works it is fun, i do have a few pointers
1) It great you made multiple levels but i would advise to make a bit less of them and really nail the ones you have, there where levels that where very hard to complete because the pumpkin could only fit in a certain way and you had little influence on how it was orientated
2) I am not a game design expert by any means. But some of the candies placed (especially those in the end) are there to be never eaten else you cant finish the level, which bothers me because for my feeling i cant "Complete" the level
3) Much made mistake at first games but the physics was a bit of i could just stick halfway a wall in the air as long as i kept left or right pushed
4) A nice to have is to be able to see what levels you completed
But as i said with a bit of fiddling here and there i enjoyed playing it so good job
