Hrm..
Read the last review...AND..to help you, I would suggest if it's his "Special Beam Cannon" (Makankosapou) then you should find a site that has that wav file and use it for a sound effect. ALso, th game's glitchy in the sense that you can go below the bottom of the screen, and beynod the left boundary.
Finally..if you don't mind me asking, where'd you get that picture of Piccolo (that's used in the top left corner of the HUD)?
