I really didn't expect the para_nulla part lol! It was a struggle to draw using my mouse since i only ever use that to click and scroll... It ended up with a very ghost-like nulla with short hair and a more (different?) looking face :d. I also decided to give the flower that mary likes to nulla. :p Also, I like Unum's route as much as Nulla though, but perhaps it has to do with shams and Noor. mah non-existent computer babiess :d 
Could you guys explain me the para_nulla part please?? I'm on nulla's path and after i see his past we talk and he says he needs time and the heart/corazon text opens and the game closes. Idk what to do after that, I've tried to change the parati(or smth like that?) image's name and made it para_nulla, deleted all the files, reopened the game and came to that part but it still didnt work:(( edit** turns out its the memory path and its just up to that part sorry guys i guess i gotta wait for it first
