I am completely helpless at these types of platformer & can't for the life of me get past the elevator section, but I love how polished & tight this game feels.
The music/sfx is on point, art work is great & I especially love the subtle change in the level depth/look when the player flips left/right.
My only piece of feedback would be : could we get more feedback to indicate when the parry becomes available ; maybe a faint circle collapsing back towards the player would help with timing things.
PS : No offense to your artwork but I feel your thumbnail really undersells the game ; perhaps a crop of the character in game would draw players in more readily.
