GlintBaffleRotunda

Portrait endless beam-swinging. A prism sits at the centre of the rotunda and the finger circles it, pointing the beam wherever you like. Energy crystals drift around the hall and catch fire when the beam crosses them; shadows press in toward the prism from every side at once, and that same single beam is the only thing that burns them off. So every angle is a trade - light a crystal and you are not covering the shadows, cover the shadows and nothing lights. The prism does not turn quickly, while the shadows come thicker and faster until one beam cannot cover the circle however you swing it. A Strong Lens multiplies the beam's width for seven seconds so it can sweep a whole line of targets at once, and a Shadow Screen keeps the prism untouchable for six seconds and clears the hall as it goes up. Endless mode with no fixed stage.
