Hi! I say that because, in the end, both move you in the same direction, while other pools of movement serve different functions. e.g grapple and jump. What I was suggesting was to increase the overall pool for walk + run so that that it is equivalent to the separate walk and run pools so that the player is given the option to run or walk at their discretion. To compensate for the additional distance traveled through running, you could make the pool decrease faster while running when compared to just walking.
But good game regardless!
