you CAN'T make the explosion sprite bigger. It's coded. How could you POSSIBLY make it bigger, since the size of the explosion is dependent on the strength of the attack, your power level, and how much ki you put into the attack? How can you make the explosion bigger than it's supposed to be, since the size of the beam doesn't really affect how you get hit by the attack, but the size of the explosion determines whether or not you get hit by it.
