Little tip:
limit the number of corpses (and reuse the ones already placed when the max is reached), that way the corpses wont bog the game down if the player dies too often.
secondly, half of the deaths seem to come from a failure to separate pre-death momentum from post-death/respawn momentum, resulting in a lot of respawn-into-pit and similar double-deaths (that IMHO do not qualify for a corpse)
