There's a very pretty new skill tree layout. Progression should be clearer, and it should be easier to explore.
There are 5 new passive skills:
Token Thrift: 10% / 20% / 30% chance a pull doesn't use up the loaded token.
Fewer Challenges: Challenge rounds appear at 80% / 65% / 50% of their usual rate.
Curse Relief: A cursed catch sells for more.
Chain Bonus: Every ten catches in a row raises the bonus.
Sneak Peek: Holds the field still before the the catch attempt giving you a chance to see what's there.
Quest Claw: New equippable claw that shows you where a quest plush might be hiding, lets you also pin your own creatures to hunt.
Rebalanced Fusion pricing off the new skill tree.
Rebalanced all upgrade prices.
Made cursed catches worth less.
Made Focus tokens also curse catches.
Updated the "Cash Out" screen you so you can select what you want to sell. Automatically deselects quest items.
Wallet/Quest panel got some love, it can now be collapsed/expanded.
Updated the catch reveal popup look and feel.
