Currently it is possible to slice your way through the edge of the Ladon map and emerge around pirates point, The same with arena battles, Plus if you have jump jets you can fly over the walls.
I have not tried Ladon with a wilco backpack yet, But I am putting a pretty good guess that its possible to escape Ladon with the magic of Wilco.
My suggestion to fix theese "Do or die" maps is to simply bounce the character back, Or have the edge walls indestructible.
Cheers!
