Encumbrance is calculated from inventory slots filled (ignoring
count within stacks), compared to health; players can freely carry
the same proportion of slots as their health.
Players who are encumbered lose up to 80% of their walking speed
(i.e. for a full hotbar and no health).
This is another disadvantage for being injured, and an incentive
for players to take care of their health.
- Players heal over time at variable speed, depending on subtle
environmental factors.
- This frees us up to work on the death mechanic, since it's no
longer the only way to restore health and prevent an untimely
death.
