STROKE of brilliance!
maybe notIf anyone decided to work more on this and make it more then it is.

When you die, you should have become the little squirt with smaller jumps or no double jump.
Whatever I still think it would be awesome and explain re-spawn.
Maybe the operator could wobble the screen with spacebar? with a delay as not to get out of hand like maybe once a round.
When small you could do such things as;
-Fit into small holes and get the food in the spike rooms?
-Keep any food your predecessor fed you
-Be jumped on and then eaten by the bigger player?
Perhaps you could waste a food item? and puke on the floor, and make a puddle that could stick your opponent for two jump or so if that makes sense.
