When a laser loops around and reaches you three times, you suffer complete annialiation, and the beam stops bouncing.
For example, suppose your opponent has a medium red pyramid pointing at you. You have a large red pyramid pointing back at him.
- Kaxxt fires a red laser at you. The beam bounces to your opponent. One point gets past his pyramid and damages him.
- The rest of the beam bounces back to you, for the second time. It bounces back to your opponent for the second time (damaging him by one point again).
- The now-weak laser beam bounces back to you for the third time. Stack overflow -- you lose!
