I can't believe that a single person managed to make this happen.
I can see why this is a massive project, and the effort required is massive too.
The idea behind it all (put some characters from great games into one of the most classic games of all time) is awesome, and the whole thing is awesomely executed...the tips are really helpful and are integrated perfectly into the game.
The characters move and are controlled well, there seems to be nothing wrong with your game...and by the way, you should ask a mod or an admin about your problem.
I don't know what else to say, apart from "good job".
