Great game made in the time, if you would like to improve it I would recommend changing music to make it either longer or having two tracks per level, make sure to playtest with many different people to make sure you aren't ramping up in difficulty to fast. Remove the push when you jump its just annoying.
Here's a short list of what I liked/disliked
Pros -
Great animation
Very great use of theme, and limitation
Love the story being about the 3 little pigs
Fun
Cons -
Music can get repetitive at times but nothing to bad
Although the Animation is nice and crisp, I'm not much of a fan of the art style
Difficulty curve could use some work.
Jump variation makes my death feel as it was unlucky rather then me being unskilled
