Pretty cute visuals, except for the CRT filter which was a pure eyesore.
You should avoid using white for the background near the player's height, put it near the top of the screen for clouds for example, because it make the dust particle invisible when the player uses the dodge move.
I'm not a 2D platformer guy so when I say that the jump feels off I don't really know why. Could be animations or physics but I'm not sure. A good start is adding a falling animation that plays when the player velocity is negative instead of using the jump animation thorough the whole jump.
The player speed shouldn't be affected by slopes, right now the player slows down when going up slopes and speeds up when going down.
Also when the player switches left/right directions while running she should slow down and play a skid turn animation, like Shovel Knight and Mario World, in my opinion.
The top down sections were fine, no complaints there.
