Goal: Defend your central tower from invading geometric entities by rotating light beams to specific angles. You must prevent 10 enemies from breaching the center tower across 10 increasingly difficult waves.

Controls:
Rotation: Use the Arrow Keys (Left/Right) or the on-screen ◀ ▶ buttons to rotate the selected beam in 15 degree increments.
Aiming: Click or tap directly on the circular grid to snap a beam to that specific angle.
Selection: Press 1, 2, or 3 to switch between active beams.
Advance: Press Enter or the Next Turn button to fire the beams and move enemies forward.

How it helps: This simulation strengthens geometry and angular reasoning by requiring you to visualize a 360 degrees space divided into 24 sectors of 15 degrees each. It challenges you to calculate beam coverage (arc length) and predict enemy movement along a circular coordinate system.
