11.5 sounds like the time on a clock, anyways here's the notes:

Fixes

o Fixed a bug where dropping razor after getting hit would make you lose your stored ability as well
o Fixed the control settings from not lining up with the icons
o Fixes some bugs when restarting after doing certain mechanics or cutscenes
o Currently fixing bug where the world cursor is stuck in a glitched spot when starting a new save file

Additions

+ Added the Void ability! Throw black holes and teleport in the air with this Unfurl power!
+ Added the remaining BG effects for abilities! (These being Frost, Reflect, Void and Wind)
+ 4-3 is playable
+ 4-4 is playable
+ New sprites for Cappi when jumping from a stomp, hitting a spring and walljumping

Changes

o The Reflect Shards that Shine creates can be pulled in with Wind's up attack and Void's black hole
o Mun quotas are lower for every level, meaning that you don't need every mun to get the red star in a level!
o EXPERIMENTAL - Shock's speed boost is no longer on Shock. It is instead a universal mechanic where you go faster depending on how high your combo is (the values determining this are 10, 20, 30, 40 combo)
o EXPERIMENTAL - Shock gives you two mid air jumps instead of three
o Walljumping is faster
