elevators

Browse Source 
jump now applies the velocity of the block you jumped off of
  it might feel slightly different if you play n-gon often
  it could add some bugs so let me know

elevators have more realistic physics
  you can jump off them when they get to the top (fun!)
  blocks interact with them in a more healthy way (no bleed through)
  they can have a wider range of healthy speeds
  it can hurt mobs

platform: jumps a bit before moving up
you can't use set position for y, because blocks drag a bit inside the platform
get delays working right
do something if the force is overwhelmed so much the platform moves backwards, or below lower/upper range
apply a constraint when still and remove it when moving
also apply thr constraint if the block goes outside normal bounds by too much
should jump velocity add to current velocity?
maybe only add the velocity of what the player is standing on
mob: molecule shapes - 2 separate mobs joined by a bond
use constraints: just spawn 2x or 3x groupings
low friction so they can spin around
spin when attacking player?
increase constraint length when attacking
