I been speedrunning Get Out of Town lately, it's a game included on the Blu-ray of the 2012 film The Lorax, it has 3 levels, whenever I request a game that has less than 5 levels it always gets rejected, I was wondering if Blu-ray games or even DVD games in general are allowed when requesting a game?

I mean a game is a game, whether or not that game meets the site’s criteria for being accepted is another matter entirely. I don’t know anything about the game you’re describing but it sounds like it wouldn’t be accepted on the basis of being short or trivial (given that it only has 3 levels).

I mean I'm also not a member of site staff so I can't speak for them (like I said, just my opinion up above), so you can still submit it provided you can get a run recorded of it.  Just use your best judgement when submitting games so as not to clog up the request queue - which is already sufficiently backed up - with a game that goes against the rules on the Request Game page.
