Dragonfire
Let a fireball catch your legs just as you leave the treasure room,
this seems to hurt the next player more than it does you.
Jump, then immediately pull opposite the direction you're facing
(keeping the button down), you'll seemingly run "backwards" for a bit
before turning around. (nothing useful really.)
Frying may cause all prizes to be of one type and in a column. If
you fry until the game starts with a black and white castle, all
prizes will be in a row and look like the word "in". The dragon will
spout few, if any, fireballs. Touch one of the prizes without
running it over and you just keep collecting points, nonstop!
