I was not sure if there was an update- no update notes or such, but now I checked it and noticed that wall-jumping is way better (but still, could be possible that if player press a direction key oposite to wall, while he is attached to it - he don't fall?)
Also I like that there is possible to use more keys for jump ^.^ feels a bit better to play this game now - still is not so responsive but I guess thats a challenge ;p
