Movement speed selector affects climbing ability

[Vectorus]

If you lower your movement speed setting enough (Shift+M), you'll find that some fairly gentle slopes become impossible to climb. Most notably man-made inclines such as stairs and ramps.

Should the movement setting affect only top speed, not acceleration? Presumably that would solve the problem.

[Haxus]

The control reduces your movement force.

Top speeds and jump distances vary according to DNA and environmental conditions.

Top speed in zero G vacuum is light speed.
