I have three things; a comment, a question, and a suggestion.
1. Annie + Scorpion = BEST F#CKING ANIMATION EVER.
2. A previous user mentioned this, but there are three missing gallery animations, just after the Annie/Spider and before the Scorpion. Am I missing something or...?
3. In lvl9 with the Ice World, Annie mentions that she saw a Snowman move, implying she saw a Snowman above ground that moved behind Hailey's back. What if you added an animation where after Hailey gets the chest and returns to the surface, you see Annie getting "snowplowed" by a Snowman, and you have to either save her or wait until it finishes before you can end the level. Just a thought.
