The player uses a laser-shooting knight in an escape room to both fend off/defeat attacking enemies (in waves) and, by reflecting the beam off mirror devices, hit a switch. During the attack waves, the player must focus on defense and does not have time to open the room’s door. Once the switch has been activated, a door opens and the player can escape. If the player fails to open the door in the intervals between attack waves, the waves grow increasingly large and eventually overwhelm the player. If the player is overwhelmed, it’s Game Over. If the player escapes, the game is won.
