- Landing in water alleviates all fall damage
- Passing through any liquid (water + lava) and cobwebs "slows" the player down,
i.e. resets the fall distance to that block, but only after checking for fall damage
(this means that plummeting into lava will still kill the player via fall damage, although cobwebs
will slow players down enough to have multiple updates that keep them alive)
- Slime blocks reverse falling velocity, unless it's a crouching player, in which case they act as standard blocks.
They also reset the topmost point of the damage calculation with each bounce,
so if the block is removed while the player is bouncing or crouches after a bounce, the last bounce's zenith is considered as fall damage.
With this in mind, we first check the block at the player's feet, then the one below that (because fences),
