I'll add my two cents to the pile that says the controls are awful. Specifically:
The windup times of the chain and the attack, aside from the crouching knife, are way too long to time hits correctly.
The landing animation halts an air attack. It's frustrating when I want to land and attack something, only to realize I've jumped defenselessly into their attack instead.
The skidding effects from even the slightest motion make it difficult to go where you really want.
The wall hiking is buggy. I can't seem to consistently time it correctly.
Maybe make her stab the wall to hold your place when you press the jump key, instead of the delayed effect.
Grabbing ledges consistently is difficult. Why use the jump key for so many wall features (grab ledge, stop descent, and hike)? Maybe make ledge grabbing automatic.
It's frustrating that enemies who spot you can shoot through walls.
I know these are nitpicks, but I think this would be a great game otherwise. You've got an excellent aesthetic to work with, and I think these are problems that can not only be solved, but would vastly improve the experience.
