The hatched chicken is literally a game changer compared to the first 100 levels of being an egg. We hope that the difference between the puzzles of egg rolling and the approach of navigating a character that can jump and run, is not so big that it appeals to different types of gamers.
Because the character starts as an egg it obviously can’t jump and run. So all the first levels are about transporting the egg on conveyer belts, planks and baskets or shooting it off with the cannon.
The egg becomes a little more mobile with legs out of the shell and now being able to walk and run. Late when the chicken hatch it also gets more athletic. It need to because dangers escalate and the game again changes gear to a more dangerous environment with hammers, saws and spikes to avoid.
