Yes, you're right in that I'm going for a somewhat more realistic style, but only to a certain point.
And well, even if I added an animation for the player to crawl up ledges the other jumping way would still be there as there are sections where you have to jump from ledge to ledge and such.
So I'm not sure if this will be worth my time, it's on the list but that doesn't mean it will be added any time soon or at all.
I get what you're saying though but.. I don't know, not very high on the list.
