Yes, but the first two endings lead up to the third ending. Starting with the sad ending makes the happy ending happier. I really don't like making stories worse for EqD. (They're also bad about first-person narrative - the pre-readers sometimes complain about first-person narrative that isn't grammatically correct.)

The pre-reader's interpretation of the word limit rule was arbitrary - the rule just says "2500 words", nothing about alternate endings. It was silly for him to interpret the lower limit on words so that removing words makes the story appear to have more words.
