Input timing not changed with framerate

[ValiantBlade]

There are many people reporting this on Steam, and I figured this should be actually put on the github. The input timings are not matched with the set framerate. From my own test with 60 FPS, I can safely say that this makes the game almost unplayable since the regular attack timings are so slim that I was accidentally attempting stripping every time I hit any of the attack buttons.
