Hit stop - a hit now slows the world down instead of freezing it.
Achievements - you can earn them now. Before, not a single one could be earned: the counters for bosses beaten stayed at zero no matter how many bosses you beat. All eight are earned by playing.
Boss achievements - Bad Dog, Siren's Call, Not On The List and Sleep With The Fishes, one for each boss you bring down.
Winning clean - Whole Chicken for winning without dying once, and Not A Scratch for winning without losing any health.
Falling - Remember Who You Are the first time the chicken falls, whether or not you get it back up, and Tis But A Scratch for falling four times in one game.
Sardines - no longer skate when they walk. Each little hop dragged the foot almost a whole body length; now it is a fifth of one.
Parry - nothing tells you when to press yet. That is next.
