WhipSlash

Interesting concept!

While obviously a prototype, the core idea is pretty neat.

Things to note:

In the tutorial, it's unclear, whether or not Parry is the last action you are taught, since it's hard to tell, if you have managed to parry an attack. Maybe add a visual or sound que, that you have successfully parried or maybe allow the parry to grant you vision. 

Being in complete darkness can get disorienting. Since the only way to get your bearings is to crack the whip, either need the whiplash to allow you to see for a longer period of time or will need to introduce other forms of extending vision time.

Looking forward to the next update, whenever it rolls out!
