hi  Arno ! did you discover some new formations? :) i've observed some new ones (in this cave). for example: 5 ff moving down-left. there are more ;)

hmmm... in my demo i do not spot any new ones, only some existing.  
  
5 ff down-left: that is interesting.   
i already know about 2 formations looking very similar: 4 bf up-right and 4 ff down-left.  nesdori  has shown in his last cave 5 bf up-right which looked a bit like the 4 bf variant. so i already wondered if there exists a 5 ff variant. i'm curious if you found it! :-)

i've realized that the forming of groups depends on how do you cut the dirt located into the ship rear corner.  
  
for now i've recreated one of these formations, so i can do a demo cave and show you this one ;) (i have a screenshot of second 5 ff formation, but for this moment i'm working on it and trying to recreate. but this will take a while, because i have not much time ;)  
  
i'll borrow the idea of  nesdori  and create one demo cave with recreated formation/formations.
