Thanks for the feedback. I'll take your suggestions and add them to the level. I'm pretty sure I lost the competition to another person. They haven't announced the winner yet, but I have to admit is a lot better than mine. It's called Final Fantasy VI: The Blackjack's Shining Battle.
Just to let you know a couple of the other boss fights include the black mage from FFI and Ultros. Ultros is hidden though.
