Sprint
Hold Shift (L3 on controller, new button on mobile) to run. There's a stamina ring on your HUD that drains while you sprint and refills when you don't. Run it all the way to empty and you'll be winded for a few seconds, so pace yourself. Crouch moved to B on controller to make room.
Talents
Your coins now buy permanent upgrades. Five talents: Jump, Speed, Cast Range, Bubble Charges and Ability Power. Put everything into fire damage, or into jumping higher, or spread it around. Your call.
Levels
Forest, Treehouse, Italy and Wild West are populated now. Actual props, actual layouts, actual places to explore instead of empty geometry.
Doors
Doors show you how close you are to opening them, so you're not guessing how many gems or coins you still need. The coin requirement came down too. Playing solo, the gem is always there now.
Fixes
Creating a private game no longer drops you into someone else's public one
Abilities and the Bubble no longer get stuck mid-cast, leaving you unable to do anything until you respawn
Fixed the Bubble occasionally firing off toward nowhere on your first throw
Jumping as host felt floaty and gelatinous, it doesn't anymore
Doors stayed shut even with the gems in hand, fixed
Gem counter showed the wrong number
Player name plates weren't showing up above characters
