Had very interesting experience with this, because I reached an ending I was pretty satisfied with, but from the comments I knew about perfect ending. So I played again and again, at some point was ready to give up like a real regressor and accept okay ending, but at the last moment when all hope was lost - I found it.  And it was worth all the loops my boy suffered through.  <⁠(⁠￣⁠︶⁠￣⁠)>
