That's almost too awesome to remove it, yet it's totally not what you would expect, i.e. the epitome of confusing for any new player (or anyone new to the Slider, which we will all be in the beginning of a stable version featuring it). So I guess that calls for a change here. The question is though whether it can actually be changed at all, because as Simon says, the Climber's behaviour is long-established, and we've just had a Swimmer physics change.
