Sending two essays in the optional supplement?

Hello,

I’m an SCEA applicant to Harvard. I know that this might sound stupid, but I was wondering whether it is okay to submit two supplementary essays or not? I wrote one on how my love for gaming introduced me to research and one on the letter to roommate. In totality, the word count is around 600. Would it be better if I wrote more on either one of the topic ?(which I believe, won’t really help much as I have conveyed what I wanted to in the current essays)

Thanks.
