I think it could have been written in something like MS-DOS edit, which doesn't have a spell check feature anywhere in sight. So it never saw a spell checker, they didn't have too much awareness of the errors. Maybe they also didn't care about spelling too much - thinking up words that fit in the spaces is fun but correcting spelling errors isn't much fun.

The document being an in depth write up of Super Metroid probably also says something about the person's character!
