haha, I thought that sounded great. But how do you reflect the sun back at him?
With a mirror of course.
This is crazy, I'm crazy, I'm actually going to follow through with this.
Obviously, you couldn't play the whole level on one table. This is one of those stories where Robotnik shrunk Sonic, btw.
So, to do any kind of damage to ol' Eggface's hovercraft, the battle takes place on another magnifying glass/curved mirror/whatever works, intensifying it even further back at him. Trick is, depending on where you're standing affects the beam's direction, jumping tilts the surface further your way. Tilt too far and you fall off and lose.
Now, I'm going to slip into my Sunday straightjacket and do some headbanging! AAAhAHAHAHAhahaahaaaaaa...
