Respawn can happen “under” an opponent worm
Related to #7, but a bit different: if a worm is over your respawn point, you can materialize “under” it, meaning your worm is hidden until the two paths differ. That’s a bit confusing.
Not sure if it would be a good idea in this case to appear on another point; maybe randomly chosen around (and empty)? or on the respawn point of an opponent? (but what happens if they are all covered?) Another solution is to not respawn until the worm has left the point, but that might be frustrating.
