It's all a matter of style, but I removed the border on the iframe that holds the video player and I liked it better because the video started to blend with the rest of the page. I felt it made it more immersive.

Cool music and the 8bit style gave me flashbacks of some games I played in the 80s.

Good luck, it looks great! (though I, too, didn't really get the gameplay or the type of game it is)
