Could you make the max stamina setting affect the air flutter? It seems that that's what the setting is meant for, as wall running usually doesn't show a stamina wheel, but the flutter does show a wheel.
I’m not opposed to giving the player more flutter time, I’d like to make it a separate slider if at all though. As for climbing stamina, it just doesn’t show up if there’s no change. For the first half second of running on a new surface your stamina usage is paused. I’m somewhat conflicted about making it fully unlimited as that’s kind of above and beyond. It’s essentially infinite double-jumps?
