Too big? I think, eg. Girl Life or Newlife are bigqerThe game size is too big. Maybe devs use this game like a cow. They don't want to reach end of developement, because how big amount of time they spend — as many money they get. Episode 1 is beter - dont have unsignificant contest and strong main line. But Episode 2 just mammoth.
And as for FB file size, I think we can expect some important news on the DM's Patreon page in a while.
