Npc/Level Linking.
 

In a future version of graal exe, a command to link levels to npcs would be useful, then we could have undersides of boats and the link on the level side would always go to the deck of that boat.. =)

if(playerx in |x-5,x+5| && playery in |y,y+5|){
setlevel2 stuff;
}
its not that hard to code

I think soul blade managed a script like that, i think it was tested on ferharia but not sure.
