I really love the artstyle of this game, I could definitely see myself playing a full game and enjoying a hand-drawn artstyle all the way along.
The idea of rolling an egg is cool and makes the movement a bit more challenging, but I really didn't like the feel of the jump. The jump didnt answer to a single tap, and you had to hold it to make the jump register. Also, the fact you kept jumping while holding it down made it feel really bad. I think you should make it so as long as you don't release the jump button you cant jump again.
Music was pretty cute, some nice sound effects could have been a nice addition.
Well done on contributing to the Game jam!
