Oh climbing down.
Yea I guess that's an issue, although I've always found climbing a ladder down while facing away from the ladder (having my back towards the ladder) in FPS games a bit weird , not in terms of how it doesn't make sense but in terms of controls...like sometimes it'd make sense to have to press down to go down but the way it works is that you walk forwards towards the ladder and instantly start climbing down and I always fear that my character will just let go of the ladder and fall if I keep pressing forward...lol
That's why I just prefer a context sensitive button where in I grab onto the ladder and just go up or down with proper climbing animation. Though this is obviously not as quick.
