In a mud, need to find the words to give the player the feeling of motion,
Given the lack of visual reference. Navigation and movement is based on reference to known and supposed points in 3 dimensional space. Absolute direction is abstracted away from the player experience. Say we start with a single strong fixed reference point called home (or spawn point). The player's body knows at the beginning how far away from home they are but only knows two directions: towards and away. Only after discovering another point are they able to add relative movement by fixing how much towards or away from the two reference points they are. Even two points is insufficient to place a body absolutely. One would need a minimum of three known points to narrow down possible position to two places. Even this... is goings to be iffy.
But it doesn't matter because bodies always know how to get to places they know, unless they don't. But the player can't really help the body. They player can perhaps decide how to respond to the uncertainty. * Relative three (or 3.5) dimensional movement.
# Pursuit and Escape In this world if a body was fleeing from another they could simply try to move randomly and evasively but risk ending up in unexpected places. On the other hand a body could aim for a particular destination. This is a good way to avoid getting lost or into worse trouble but your pursuer has a chance of guessing your intended destination, (if they have their own personal knowledge of it).
As a pursuer, if a body guesses where its prey is heading, it has the option of trying to beat them there. Different factors might affect the outcome of the race. But I think merely following a quarry with no knowledge of its intention puts a pursuer at a disadvantage. Knowing the destination at least removes that - but it of course leaves the possibility of being misled and losing the quarry entirely.
As a quarry, the best escape destination therefore would be one the pursuer is unlikely to know, something obscure perhaps. Keeping a list of good hiding spots is a valuable survival strategy. And with a [[kiss]] a body can share all their known locations with another body. So be careful who you kiss.
